more questions for you. What would Duergar, Derro and Svirfneblin be like in Eberron? Where would they be found? I think Derro would definitely be some creation of those abberation guys whose name I forget lol. But what about Duergar and Svirfneblin? Derro are in the Mror Holds, and mentioned in Exploring Eberron. Duergar are in Sarlona, and discussed in Secrets of Sarlona. I haven't personally incorporated Svirfneblin into my Eberron.
