Nice post. I guess actually I'm probably wrong about the earth magic, at least in so far as clockwork horrors and stuff might actually be quite in keeping with skaven crazy engineers.
I think I agree with pretty much everything in the last two posts actually. I hadn't realised how much warhammer i'd forgotten. Warpstone and warp lightning had completely slipped my mind! The only thing I'm unsure about is nature magic. Maybe they could have the odd N1 random for cross breeding as you suggested Sombre, but I think more than that would be a bit unthematic, as they're hardly in tune with nature.
This project definitely gets the current prize for "thing llamabeast is most excited about".
