I saw the robe today on a GM-controlled NPC (she said it was the Robe of the Evoker) for a GM quest on Tunare. The NPC was Ta Lalila, who is (I assume) someone in Felwithe. She was a High Elf Wizard I believe.
The robe looks absolutely gorgeous. I can't even describe it. It's white with a brown stripe down the front, with a two-layered neck. Circles on the back and arms.
Certainly a must have piece for a robe collector, or someone who actually does the RPG part of EverQuest.
