Jedi-like groups in other worlds?

I'm trying to get my thoughts about the Jedi in order. (I finally have a Star Wars icon, even!) For comparison I'm looking for other canons that have people with special powers that are sometimes born among the population and whose existence is general knowledge.

So far I have:
- the telepaths in Babylon 5
- the mutants (or other super-powered people, but mutants fit best) in X-Men/Marvel and other superhero stories
- benders in Avatar:tla and LoK, though they're a bit more wide-spread
- chakra users in Naruto
- wizards and witches and magicians in several fantasy worlds: right now I can only think of Tortall and Emelan, but I know I'm missing some obvious ones, even excluding the many I don't know. Uprooted qualifies.

Which other groups/worlds can you think of?
