Warpweaver Hashom

Warpweaver Hashom is an ethereal transmogrifier located in the Canals of the Alliance capital of Stormwind. He manages the shop The Three Winds alongside fellow ethereal Voidbinder Sturzah, Vaultkeeper Razhid, and Thaumaturge Rafir, in which he may also be found. He is responsible for offering the service of transmogrification to those who desire a new look for their armor or weapons.

Trivia
Warpweaver Hashom is an anagram for 'A WoW Revamp Rehash', which could be a nod from Blizzard Entertainment developers to complaints that the Cataclysm had too much revamped or rehashed content.
