Avadon - Interview @ Inside Mac Games
Inside Mac Games also has a short interview with Jeff Vogel about Avadon. Not much is revealed but it's worth a read for fans:
FP: Are you planning on having clear-cut good and evil factions, or will everything be a bit grayer in Avadon?
JV: I want almost all of the moral choices in Avadon to be pretty gray. You are warriors tasked with uncovering people who pose some sort of threat to the Pact, the alliance you are from. However, when guilt is ambiguous or when the tactics you employ can be pretty questionable, in the end the player will have to make a lot of tough (or cool) decisions.
