There are two options for setting. Option 1) Either Birthright.net possesses and makes available for download, or someone possesses and can distribute, a map of Anuire, in which case we'll be using the Anuirean domains, or option 2) neither of those is the case, and you'll create your own domains rom whole cloth in Brechtur.
The emphasis will be on domain actions, as the pace of PbP is better suited to that, but if anyone has the time to devote to running actual adventures, I'll be glad to do so. I'm thinking that I'm going to eliminate the wizard class entirely, using the sorceror for elves and the blooded (thus switching the elven bonus to Int over to Cha, and changing their favored class), and use the adept with arcane casting and a modified spell list for the magician, as it's truly an NPC class at heart. If anyone objects to these changes, or has more ideas on the adaption, feel free to let me know.
