Dred: I wasn't planning on accepting people on a first come, first served basis. So depending on how much interest is expressed I might lock it out for you. I'd say go ahead and get brainstorming though, worst case scenario would just mean we need to add more Planes into the mix. 

Khan: Depends how you are going to design your faction / champion. A more spectral approach would probably fit better in the Wraith Lands; a faction designed around literal shadow would be a better fit for the Abyss.
