Well, I don't really want players to be able to use the mages who predate the new order, though there will be some. As stopping aging is a rather advanced thing. However, since the conflict, a lot, A LOT people have died. As such, only roughly 30% of the land is considered civilization. The rest is a wild and dangerous place, with remnants of the previous age in ruins, wild beasts running amok and snacking on the unwary. And of course, anyone not wishing to a part of said civilization.
