i was wondering whether you have thought about introducing warlocks (or something similiar) to astlan.
since some demons have lots of animus and mana (or special abilities) available, they might consider sharing some of it (perhaps similiar to a priest – god relationship) for a price.
basically they could turn any indvidual into agents with lots of power with little need for training (which could prove an effective recipe for disaster).
demons of astlan was great!
characters, magic, the “bad guys” beeing the protagonists … there is nothing not to like (except maybe that its only 600 pages long 🙂
