I still play on illidan, but I'm no longer part of the Guild. The Guild still exists though, but my guess would be Grav is the only one left in it, maybe with a few exceptions, because he never really got rid of the guild, he just quit the game.

Irokas and Hantu still play on Illidan as well, although Hantu moved to another server and plays there a ton more. Irokas is level 60 now.
