Ritualist Trainer ??? Were are they???

Can someone list the locations please??

Thank you.

Any NPC with the tag [Skills] can teach you skills. This game isn't like World of Warcraft, for instance, with separate trainers for each profession. Just one dude with skills for all!

If you want to know a list of all the trainers in-game, though... http://gw.gamewikis.org/wiki/Trainer_locations
