Another note, I may be allowing the Scout (Complete Adventurer), the Favored Soul (Complete Divine), the Knight (Player's Handbook II), and the Warlock (Complete Arcane) as possible character classes to add a touch of variety to your options, but I have not entirely decided yet (if I do allow them, I will provide the rules for the classes to all interested players). I may also allow the Expanded Psionics Handbook (since the existence of psionics is the default assumption in Eberron). These will be entirely optional however, and in the case of psionics, are available in the Hypertext d20 SRD for 3.5. I will NOT be allowing additional spells, magic items, or feats (psionics possibly excluded) from any of these books at the moment however (I have an idea for making additional feats and spells available as rewards for completing quests, but that will come later). Furthermore, characters will be limited to no more than three classes (prestige classes included), so you might want to consider that when thinking about character development.
Magic item creation will probably be limited in some fashion as well (leave that stuff to the NPCs). However, you can expect to see a wide variety of unique (and powerful!) magic items make their appearance in the game as treasure. I will be seeking to make treasure an exciting and interesting part of the game by presenting named items with personality and history which you have never seen before.
