Dragonmarks 2/26: Teleportation, Warforged, Paladins and More!

It’s a very busy time for me right now. I just got back from Portland Comic Con, Gamestorm is coming up, and I’ve got a lot of irons in the fire. I’m itching to start talking about Codex, and in the future Codex discussions will be interspersed with Dragonmarks. However, I’ve still got a few things I want to finish up first, so for this week, it’s more Eberron questions. As always, all answers are my personal opinion and may contradict canon sources!

This week we have a few different topics: warforged, paladins of Aerenal, Overlords of the Age of Demons, teleportation, and more. First up: WARFORGED AND HOUSE CANNITH.

How do you see Warforged evolving and where do you see their race going in the future?

First off, I’ll point out that warforged are capable of physically evolving. The Reforged and Warforged Juggernaut prestige classes both involve a physical transformation; the warforged juggernaut actually grows heavier armor and spikes. Warforged are fundamentally magical entities, and they are living constructs; there’s more to this than just being sentient. So I think it’s quite possible that if you jumped forward a hundred years, you’d find a vast range of unique warforged who have adapted to different environments and circumstances.

With that said, the greatest obstacle in their evolution as a race and their future is their inability to procreate. The Lord of Blades is trying to address this by seizing control of a creation forge and finding a way to make it work. In The Dreaming Dark novels, Lei’s parents explore a different solution to the issue of warforged procreation. Following the previous path, perhaps some warforged could evolve the ability to procreate. However, if any of these come to pass, how will the rest of the world react? The threat of the warforged is limited because of their numbers. If the Lord of Blades is found to be producing new warforged, will nations or houses band together to stop him?

If Cannith permanently split into West/East/South, can you see them becoming “Corporations”, or what would happen?

If they permanently split, I think they would logically seek to become separate houses individually recognized by the Twelve; after all, Thuranni and Phiarlan have paved the way for this. The only question I see is if one of them would instead choose to ally directly with a nation as opposed to becoming a smaller house… if Jorlanna would ally with Aundair, for example. There’s also the question if any would keep the Cannith name. In the case of Phiarlan, the larger house kept the original name, and I suspect the same would hold true here.


House Orien controls teleportation in Khorvaire, but it is unclear what you are actually paying for. The Campaign setting says that teleportation is 10 gp per mile.  But they left the service description out of the book.  From reading the rest of the Eberron Campaign Setting (ECS) and having a little knowledge about some of the novels I believe the mode of transportation is a teleportation circle.  Is that true?

It depends what you’re playing, and exposes the challenge of multisystem design.

Eberron was designed for the third edition of Dungeons & Dragons. The premise was that magic of up to third level was fairly well integrated into society. Higher-level magic – such as teleportation – was not. It’s possible to pay Orien for teleportation, but what you are paying for is to have an heir with the Siberys Mark of Passage transport you using the once-per-day power of his mark. Looking to random locations where I know this is discussed, it’s called out on page 11 of Secrets of Xen’drik—which includes the percentage chance of finding such an heir on any given day in Khorvaire’s largest cities—and page 67 of City of Stormreach, which suggests that a teleporter comes to Stormreach about once every three days. So it’s a service that exists, but it’s not reliable; per SoX you could be waiting in Korth ten days before a teleporter shows up. With this in mind, I’ll note that the idea of charging “by the mile” makes no sense at all. It doesn’t make that much difference to the teleporter whether you’re going five miles or a thousand, and you’re using his daily charge either way; so the idea that you could pay ten gp to teleport ten miles is just silly. Any sort of teleportation is going to cost thousands. It’s a service that only the very wealthy can afford, and even they can’t always get it.

By contrast, Secrets of Sarlona reveals that Riedra is a nation that does have institutionalized teleportation circles and goes into detail about them. This was always intended to be a concrete difference between Riedra and Khorvaire, a reflection of the supernatural power of the Inspired and a contributing factor to the unity of their culture.

Then Fourth Edition comes along.

In 4E, Linked Portal is a level 8 ritual that allows the user to access a network of circles, described in the ritual as being at “most major temples, important wizards’ guilds, and large cities.” We address this on page 45 of the 4E Eberron Campaign Guide, stating that House Orien maintains Khorvaire’s network of linked portals and heirs perform the ritual for travelers. I show this system at work in The Fading Dream.

With that said, I don’t particularly LIKE this system. It’s too institutional and advanced for 998 YK Khorvaire as presented in Eberron, and makes airships and lightning rail travel largely obsolete. As such, unless I’m running a 4E campaign, I would ignore it completely and keep teleportation as a rare and expensive service.

If it is a circle does it function just like the teleportation circle spell or did you have a few tweaks you were planning on? If they use circles, where are they? Which leads me to another question – how frequent would the guild houses be; every outpost or town? If that is true, how are they operated?  The way I understand the teleportation circle spell is that it can teleport you anywhere.  From reading the ECS I get the impression that the House of Orien uses a connected network of circles to jump from point to point.   Which is more correct?

By default 3.5 rules, there is no circle service at all: you hitch a ride with an individual teleporter with a Siberys mark. By 4E rules, it’s not using teleportation circle, it’s using linked portal. As such it only provides direct transportation between portals. The ECG says “House Orien maintains an extensive network of permanent teleportation circles in cities throughout the Five Nations. Outside the Five Nations, circles are less widespread, limited to the larger cities and national capitals.”

Again, while it’s there to accommodate 4E rules, this system doesn’t fit my personal vision of Eberron in 998 YK. It makes travel to remote locations too quick and casual; I’d rather that a trip to Stormreach be significant as opposed to a quick stop down at the Orien enclave.

Who operates the circle? Is it a high level mage or is any house member capable of operating them? The last teleport question, how does the house member know where the traveler wants to go?  If I understand the spell correctly the caster can travel anywhere as long as they are familiar with the location.

If we’re talking circles, then we’re talking 4E’s linked portals. Which means you tell the house member the destination city and they take you to the portal. It’s not as flexible as a 3.5 teleportation circle spell.


One of the tasks that was trusted to me by the GM was creating a Paladin from Aerenal.   We felt that some of the standard Paladin abilities just didn’t fit.  So I changed a couple of things. We dropped turn undead.  We felt the undying and undead were too closely related for the purpose of what the ability did.  So we turned to Pathfinder and borrowed the Channel Positive Energy ability.  It allows the Paladin to heal injuries or deal damage to negative energy undead.   We both thought that fit the flavor of Aerenal much better.

While you didn’t ask this as a question, allow me to address it. if this is something you’re doing for ALL paladins in order to give paladins a more distinct role from clerics—which I’d argue is the goal of the Pathfinder shift—bravo. However, if you’re saying that you’d specifically change the ability for paladins of the Undying Court because they work closely with the Deathless, I have to disagree. The Deathguard—which most of the paladins of the Undying Court are part of—is specifically charged with seeking out and destroying negative energy undead, and Turn Undead is obviously a potent tool in that war. As for the deathless, it allows them to “rebuke” deathless. But what does this actually MEAN? When you rebuke undead, they are either awed (and leave you alone) or controlled. That’s the mechanical effect, but what’s the in-game explanation? To me, it’s a matter of the deathless voluntarily recognizing and respecting the authority of the paladin. It is no different from a police officer flashing his badge and demanding that people either stand aside (awed), or commandeering civilian resources to deal with a crime (controlled). If you portray the deathless as fighting against it and being forced to comply against its will, it seems highly inappropriate… so don’t. Portray the deathless as choosing to alter its behavior of its own free will because of the paladin/cleric’s display of divine authority. The Paladin is the agent of the entire Undying Court; if the paladin is high enough level, that gives them enough clout to ask a favor of an individual deathless.

With that said, if the power is abused for trivial purposes, it is just like a cop commandeering your car and then using it to buy donuts. He could DO it, but if you report it to his superiors, he’ll get in trouble for doing it. A paladin who abuses his authority—rebuking without good reason—should suffer the same sort of disciplinary action from the mortal authorities of the Court.

And bear in mind, any positively aligned cleric/paladin can rebuke deathless. A paladin of the Silver Flame or Path of Light can do it. If you follow my interpretation, this is because the Deathless recognizes them as agents of a benevolent divine force and chooses to work with them; it’s interagency cooperation in the name of greater good. If you take a forced-into-slavery approach and take the power away from Aereni paladins, you have the strange situation of Kalashtar paladins being able to command deathless when the Deathguard can’t.

Where I am struggling though is the spells.   With the background of all the arcana in Aerenal should the Aerenal paladin have access to arcane magic instead of divine?  

A lot of people focus on Aerenal’s arcane achievements. In 4E people sometimes ask if Aereni elves should have a bonus to Intelligence instead of Wisdom. But bear in mind that while Aerenal is relatively advanced in matters of arcane magic, its greatest achievement by far is divine. Aerenal has created a god. The Undying Court is the only active, sentient force in the setting that wields full divine power. It’s equivalent to the Silver Flame, but you can actually go and talk to the beings that are a part of it. And an Aereni paladin is a direct agent of than conscious, active divine force. Frankly, no one has a better justification for wielding divine magic than an Aereni paladin, called by the Court to act as its hand in the world. If you want to reflect the tradition of the arcane, multiclass as wizard. You could even use something like the Silver Pyromancer PrC from the Silver Flame. But I see no reason to take away an Aereni paladin’s divine spellcasting ability; if anything, I’d expand it.

Turning from the divine to the demonic, it’s time for OVERLORDS AND THE UNDEAD.

Is there a list of all the rajah already published somewhere? With the rajah’s theme, location and where to find the full writeup?

I’ve never done it. However, Lord Gore at the WotC forums put together this list, which may be the most comprehensive around.

  15. Yad-Raghesh (The Vale of the Fallen Rajah, Argonnessen) colossal two-headed overlord DoE page 50 “dead”

I believe that Sul Khatesh is the only one that’s received a complete 3.5 writeup, in Dragon 337. I’ll also note that I prefer the term Overlord. “Rajah” tends to get subsumed into “rakshasa rajah”—and while the Overlords rule the rakshasa, they are not themselves rakshasa.

Is there any connection between Katashka the Gatekeeper and other prominent undead-themed entities (eg Vol and her followers).

Not according to canon. However, you could always decide that Katashka is connected to all negatively empowered undead, whether they know it or not… and that Vol, Kaius, and other influential undead are all secretly pawns in the Overlord’s plans. This certainly seems like a fine approach for starting with the Emerald Claw as a heroic tier threat, moving to Vol herself in paragon, and then bringing Katashka in as the true epic threat. For those wanting to know a little more about Katashka, check out Dragon 337 or this Eberron Expanded article.

I just read the original ECS and it gave the impression that the Blood of Vol worship/idolize undead, when I recall that this has been clarified as not true in later books; what is going on with the Blood of Vol?

I’m not sure exactly what the question is here. You are absolutely correct that I consider the depiction of the Blood of Vol in the original ECS to be flawed. They don’t idolize undead; however, many or their martyrs and champions ARE undead, which can cause others to think this. Later books give a more rounded view of the Seekers. Here’s a quick description I wrote a little while ago…

The Blood of Vol is based on the question “What just god would allow suffering and death?” – with the conclusion “None, so the gods must be our enemies.” It’s tied to the fact that the people of Eberron KNOW what the afterlife is like, and it’s not pretty. The Elven religions seek to avoid going to Dolurrh; the Silver Flame believes its people join with the Flame; and the Vassals say “Well, we go to Dolurrh, but you just don’t understand what it really is.” The Seekers say “You’re kidding yourself. Dolurrh is extinction. But we have the divine spark within us. We can become gods – and even if we can’t, we will spit in the face of death.”

What I really need to do is to get all these Q&As organized into a master list by subject. Until then, take a look at this Q&A – there’s a lot about the BoV there.

And finally, a little RANDOM STUFF.

I’m sorry if this has been asked before, but you said the scale of Khorvaire was incorrect. How so?

I feel that the Five Nations should be on the scale of France and England; by the original maps, they’re on the same scale as Russia and China. It’s a question of travel time between nations, the logical impact an army traveling on foot can have, and similar things.

Apart from some druids, are there people that consider magic as dangerous or evil? What if its use did caused the mourning?

If it caused the Mourning, then you might want to listen to the Ashbound and Children of Winter or there might be another Mourning soon. I don’t believe we’ve specifically described any antimagic groups in canon, but I’m sure there are some out there.


Dragonmarks 1/25: Codex, Cannith, and Changes I’d Make

It’s been awhile since I’ve done an Eberron Q&A, largely because I’ve been spending most of my spare time working on my new setting, codenamed Codex (working title only – it’s my Blue Harvest). But I don’t want to neglect Eberron, and a few of these questions segue into my upcoming Codex post. As always, my answers are just my opinion and may contradict canon sources: it’s up to you to decide what to use!

If there were anything you’d change about as-published Eberron, what would it be? What would you add or expand?

Lots of things. I wish we’d had more space to talk about the planes and undersea nations. I’d like more information about the spells and weapons used during the Last War, and more information about what war in Eberron actually looks like (and how these things could affect a post-war story). I wish we’d been able to provide more support for goblins as PCs. I wish we’d gotten the scale right on the original map of Khorvaire. Most of these are practical things that I believe would improve the setting for other players & DMs. There’s other changes that are more about what I want in a world, but don’t necessarily serve anyone else’s needs. I’d like the history of Galifar to have been shorter and a little more dramatic. I’d like more restrictions on resurrection and more of an exploration of its impact on society. There are lots of other little details like this, but they’re more for my peace of mind than because they interfere with people’s ability to enjoy the world.

As you progress in future RPGs/settings/etc, are there themes you tried exploring in Eberron that you’ll try to explore more?

Certainly. Looking at just a few…

  • The Impact of Magic on a Society. Any time I’m working on a world or system that involves magic, I want to seriously consider its impact on the world around it, and how it could be incorporated into a culture. Codex is at a different point in the history of magic than Eberron, and there’s more of a breakdown of different cultures employing different forms/schools of magic. But the basic idea—if magic exists and is reliable, how will it change the world—is definitely there.
  • War. There are many different ways in which war can generate stories. Eberron dealt with a civil war shattering a major kingdom. Codex will do something different… but war and its impact on the people caught up in it is certainly a theme that will be present.
  • Dreams. I’ve always loved exploring dreams. The very first RPG piece I had published was essentially Inception rules for Over The Edge. I wrote Oneiromancy rules for Atlas Games’ Occult Lore. Eberron plays with the Dreaming Dark and the Kalashtar. Codex is going in a different direction, but dreams have a role in the world.
  • Divine Mysteries and the Importance of Faith. Codex takes a very different approach to the divine than Eberron does. But it is still a world in which faith matters, where the absolute nature of the divine remains a mystery to mortals.
  • Shades of Gray. There’s always a place for the cut-and-dried pulp villain; when you fight the Emerald Claw, you generally know you’re doing the right thing. But as a noir fan, I want the world as a whole to be less black and white.

That’s just off the top of my head. I like conspiracies and intrigue, so you can be sure you’ll see a lot of schemes going on. I like to think about monsters—what are their cultures and drives? If I took another ten minutes, I’d likely come up with ten more answers, but I’ll get to those in the future.

Do the Five Nations have or seek to have colonies?

Colonization isn’t a strong theme in Eberron. By the numbers, the Five Nations aren’t even fully utilizing the land they currently claim; there’s no desperate need for new land. Beyond that, there’s not a lot of appealing land to colonize. Sarlona and Argonnessen are already taken, the Frostfell is hardly appealing, and Xen’drik is a cursed, twisted land full of dangerous things.

With that said, colonization and exploration are themes I’ll be exploring in Codex.

The Silver Flame infamously conducted a pogrom vs. lycanthropes. Has it similarly campaigned against other supernatural types?

Sure. Remember all those demon overlords trapped in Khyber? They’re the end result of the very first Silver Flame pogrom versus a supernatural threat. Of course, that predates HUMAN worship of the Silver Flame. In modern times, there’s nothing on par with the purge of lycanthropy, but in part that’s because there’s never been a threat that called for it. The Purge was a response to a massive outbreak of infectious lycanthropy; if left unchecked, this would have consumed and destroyed human civilization on Khorvaire. The forces of the Flame met this head on, and once it was broken, took steps to eliminate it completely. If there was, say, a zombie apocalypse, they’d act with the same ruthless efficiency to hunt down and destroy all vectors of zombie infection. There hasn’t been such a large-scale obvious threat, and so we haven’t seen such a thing. But on a smaller scale, the Silver Flame is CONSTANTLY campaigning against supernatural threats. That’s the purpose of the Templars: Protect the innocent from supernatural evil. Are there ghouls in the graveyard? The templars will check it out when they arrive. Is Dela possessed? Call for an exorcist of the Silver Flame! People often see the Silver Flame as intolerant or overzealous, but it’s important to remember that Eberron is a world where there ARE rakshasa, vampires, and demons abroad in the world, where you could be possessed or where evil from Khyber could burst onto the surface at any time. If it does, the Templars are charged to face it and if necessary, to lay down their lives to protect you from it.

Is there a Cannith family tree w/the prominent family member’s dates of birth/death & so on? How old was Norran when he died?

I’ve never encountered or constructed a full Cannith family tree. I don’t believe there’s a canon source as to Norran’s age, so it’s up to you to decide what best suits your story.

Also would warforged eventually expire if sealed in a vault? If Cannith seals unwanted creations up, do they last forever?

Warforged don’t need to eat, drink, or breathe. As such, a warforged could survive for a very, very long time if it was sealed in a vault. Do they last FOREVER? That depends on the environment. If you stored a suit of armor in this vault, would it still be intact and usable in a century? If the answer is “yes,” than a warforged stored in a similar way would also survive. If the environment lends itself to decay and corrosion, and if circumstances prevent the warforged from maintaining itself, it could fall pray to rot or corrosion. On the other hand, if it’s capable of moving and tending to itself, it could probably hold these things at bay. As defined, warforged have no set “expiration date,” and there are canon sources that deal with warforged created during the Age of Giants that are still operational.

Can a rakshasa truly worship the Silver Flame? If not, why don’t Silver Flame priests detect the evilness of disguised rakshasa?

This question originally dealt with the plot of a specific novel; to avoid spoilers, I’m addressing the general point. First, I don’t believe that a rakshasa can truly worship the Silver Flame… because if it does, it will cease to be a rakshasa and become something else. Immortal fiends are essentially incarnate ideas; if the idea changes substantially, I maintain that the creature will become something entirely different. A fallen angel becomes a radiant idol or a devil. A “risen” rakshasa would likewise take on a new form… perhaps that of a deva.

Given this, how do undercover rakshasa avoid detection? They have to be able to duplicate the powers of the roles they seek to fill. A rakshasa posing as a silver pyromancer has to learn some way to make his magic LOOK like that of a true silver pyromancer, even if it’s not. However, the Lords of Dust have had tens of thousands of years to work on this.  They have access to epic level spellcasters and hordes of treasure amassed since the dawn of time… so they can use magic items to help their disguises. One of the most important of these is the Mask of the Misplaced Aura, described on page 170 of Sharn: City of Towers; this is an amulet that gives the wearer a different aura for purposes of divination. So a rakshasa could have a MotMA that makes him show up as a 10th level lawful good cleric, even though he’s actually a 12th level lawful evil sorcerer/outsider.

What would change if the Twelve creates some magic equivalent firearms just for dragonmarked heirs?

It depends how effective they are compared to other weapons, from crossbows to eternal wands. Can they by any dragonmarked heir, or just one with a dragonmark? Do they require martial training, or are they mystically accurate (more like a longbow or a wand of magic missiles)? What’s the range? Do they automatically penetrate armor? How expensive are they—can every heir have them, or are they as rare as high-level sorcerers?

One of the underlying themes of Eberron is the uneasy balance of power between the nobility and the dragonmarked houses; the military power of the houses has been held in check by the Korth Edicts. If the houses acquire this new tool, there is the chance for them to be seen as a new military threat. I expect that the Five Nations would seek to ban them, just as they shut down Cannith’s creation forges. The question is if the Twelve would defy them, and what would happen if they do. Will all the houses stand together behind the Twelve, or would some break ranks? Are the nations prepared to forgo the services of the houses to enforce this point? Might they convince the Church of the Silver Flame that these firearmed dragonmarked heirs are a supernatural threat that endangers the innocent?

Ultimately, I think the answer largely depends on diplomacy and how these things are used. If they are used sparingly and in accord with the laws of the land, they might go largely unnoticed. On the other hand, if the houses flaunt them and engage in acts of aggression, it’s possible you could have an entirely different sort of Next War on your hands.

You mentioned a pulp hero named The Beholder. Would he be more like Batman or The Shadow?

The Beholder and her tagline (“No evil escapes the eyes of the Beholder!”) was inspired by the Shadow. The Beholder was a kalashtar with an assortment of agents (her “eyes”) she could communicate with telepathically to coordinate her war on the villains of Sharn.

Why may Aereni be interesting villains?

Hmm. The members of the Undying Court are tens of thousands of years old. They are one of the few forces who are capable of interpreting the Draconic Prophecy. Together, they wield divine power on par with the Silver Flame, if not as far reaching. They are capable of ruthless action in pursuit of their own interests, as shown by the extermination of the Line of Vol. Their power is limited beyond Aerenal, but can still be channeled through their priests and paladins. So, here’s a few ideas.

  • Take a page from Fringe. The Undying Court has been watching humanity for thousands of years. Now it acts. Through some unknown method, the Court extends its power to (Sharn/Stormreach/wherever), allowing them to wield their full divine power in this region. This allows them to shatter any organized military force that challenges them. Aereni soldiers commanded by deathless paladins seize control of the region and place it under martial law. They are constructing eldritch machines that will extend the range of their powers and allow the Ascendant Counselors to leave Shae Mordai. First off, WHY? Are they trying to save humanity from itself? Is this really an attack on the Lords of Dust/Chamber/Erandis Vol, who were about to do something big in the area?
  • Take it on a smaller scale. Aerenal decides that it won’t put up with the people of Khorvaire providing aid and support for its enemies (Erandis and the Emerald Claw). It begins to send military strike teams into the Five Nations to attack the Emerald Claw, and to hit areas with divine strikes. Aerenal considers these actions fully justified and is unconcerned about collateral damage. As an adventurer, you can easily get caught up in conflict with these forces, especially if you have any attachments to the Blood of Vol. Do you fight them? Strike back at Aerenal? Or try to help them finish their mission as quickly and efficiently as possible to minimize collateral damage?
  • If you’re an elf, chances are your ancestors at least passed through Aerenal. That means the Court knows something about you. Perhaps you have an ancestor on the Court. Or you have an ancient enemy on the Court who has been slowly eliminating your entire line. He’s finally gotten around to you. He’s coordinating strikes from Shae Mordai. Not only do you not know who he is, you don’t know the basis for the feud. Can you find the answers to these questions before it’s too late? How do you reach him in Shae Mordai?

Our local group is trying to get a better understanding of airships, which has made us curious about some of the choices used.  In the campaign setting book  airships use fire elementals and galleons use air elementals.  It just doesn’t make sense to us.  Why not just use air elementals for both ships?

A galleon uses an air elemental to generate wind which it harnesses with sails. The fire elemental works more like a rocket. With that said, some airships do employ air elementals; Pride of the Kraken from Principles of Fire used both an air and fire elemental.
I have been doing some research on flying fortresses.  In doing so I stumbled across a forum post that was speaking about the command center.  The post mentioned that it uses three bound elementals, earth, air, and fire. How does an earth elemental aid the flying fortress?

I don’t believe it’s my post, so I can’t say what the original author intended. However, I could see it as possibly being less about the interaction with the earth and more about enhancing the structural stability of the vessel.
If an elemental vessel loses its bound shard or it becomes damaged can it be repaired? Better yet can it be replaced?

Provided that it survives the experience, sure. If someone removes it while it’s docked, it could be replaced. And a galleon could lose its shard and continue under normal windpower. However, a large airship that loses its shard while in motion is going to crash, so a new shard is the least of your repair issues.
If shards are replaceable, would it then be possible to have a vessel that could swap crystals to take on different traits?

I don’t see why not. This would be an argument for a ship with multiple bound elementals—so you could still have one active to maintain the stability of the vessel while you switch out the other.
It seems that all of the Eberron publications only intend for the core elementals (air, earth, fire, and water) to be bound?  Do you have plans for the other elementals?  I know I do.  Is it possible that they can’t be bound?

I think any elemental should be able to be bound. I have no plans for them, but I certainly encourage you to run with the idea.

Besides Q&A it would be cool if you write short Eberron stories (FR authors do it).

I don’t know what FR authors do, but there’s a few factors here.

First, Eberron is the intellectual property of Wizards of the Coast. If I wrote an Eberron story, they would be within their rights to order me to take it down or change it. Would they? I don’t know. But they COULD. There’s been issues in the past as to whether I could post an Eberron adventure on my site. And there’s certainly no way I could sell an Eberron story.

This ties to point number two, which is time. I don’t have a whole lot of it, and the freelance RPG business isn’t the most lucrative job in the world. As a result, I need to focus the time that I have on projects that I feel are going somewhere. I’d LIKE to finish the stories of Thorn and Daine and Lei. But those stories belong to WotC, and I can’t afford to work on a story that not only can’t I sell, but that I might not even be able to post for free. Hence my working on Codex. I want to work on something that I know I can expand. So I’d be thrilled if WotC authorizes me to do more Eberron fiction. But it’s not something I’m comfortable investing time in without that authorization.
