This NPC starts the access quest for the Shimmering Citadel, but only after you have completed the quest "The Name of My Forefathers" from Zeke Two Tone in Maj'Dul.
This beautiful young lady is a hailable NPC that so far does nothing. She located on Naga island north of "the needle" road. She is standing infront of a mirror which will teleport you to the floating island far far above. That zone is filled with 60+ epic encounters on their own faction(a few books and pages can be found up there) The front of the cave she is hiding in is guarded by 2^^ 56+ nagas.
