Haz

Haz was a wizard and a member of the Shadow Thieves in Athkatla, Amn. He was involved in the covert war between the thieves and Bodhi's vampires.

Gameplay
If the player sided with the vampires, then Bodhi sent them to kill Haz in order to gain the key for Aran Linvail's base. If the player sided with Aran Linvail, Haz will be waiting in the Lower Tombs of the Athkatla Graveyard with a golem, willing to help you defeat Bodhi.
