There. You now have all the magic items you could ever want in the game, you have a very valid reason for no full casters on the material plane (no one to teach the wizards, sorcerers don't exist/have been weeded out of the bloodline/are the ancestors of the other casting types and have evolved, and the gods are blocked from giving clerics power on the material plane (perhaps it deals with that plot point).

You can use wizards and other full casters as NPC's and BBEG's in the end game fairly easily (they may not be present in body often but they have a large hand in material plane stuff) as well.
I see that done a lot, but honestly? I'd rather see the interesting developments of a world COMPLETELY free of Arcana and the Divine.
