I would like to see a wizard's tower mode or some such instead of spindlies CORRUPTING my dwarfiness.
The wizard is basically a great big noble-like git who won't do labour outside of researching way to pervert the natural magic of the plane, white tower tripe, making magical junk, scrawling runes and crap on any suitable surface he can get to and casting.
All the hard labor is done by his school appropriate servants. Golems for earthyness, and zombies for baddiness and all that stuff. Obviously they are going to eventually rebel and snap him like a twig (magicky and learny skills shouldn't up your stats), or he figures out a highly lethal demon summoning spell or some other magical mishap. And that's the way the caster crumbles.
Magical schools should be genned to be based on the organic magic of the plane and their own organic concept, they should be able to recruit members of any race depending on the appeal they have to said race. Religious orders should be based on the Gods and objects of worship.
Religion knights and such go after each other and the magical schools with ample smiting (in their God's flavour). In the case of objects of worship, followers should be able to somehow resurrect them.
The strength of the spells and invocations should vary. Most should be weak to utility strength, whilst a few should be grossly overpowered with little ground in between. If you are mining the very nature of a world, the strength of the discoveries will vary like how in reality the atomics trump all the other weapons.
