Oh, I'm not sure that I'd QUITE call it appocalyptic (although there may very well be appocalytpic plots). More just really dark (as in dark ages). Just don't want to give you the wrong impression. I'm shooting for a level of midiieval realism (plus magic of course) few games go for, so it can be very oppressive, if the GM wants. Of course, its pretty easy to control the level of grimness in your own game sessions by the people you meet, so you shouldn't feel constrained by that, but that's the baseline I'm shooting for.
