Hawezar is located to the east of the eastern continent od Sanctuary.
Witches and zealots call this snake-infested swampland home, scouring the murky depths for ancient artifacts. The unaware will quickly find themselves in dire straits.
Blizzard has described the zone as follows:
Hawezar is so deadly, the fauna is ravenous for your flesh, the floor is poisonous. This is a place of madness, of black magic. Who can tell how much of what you see is real, or just some kind of fever dream? Those that come to Hawezar, they do so to be forgotten, to be lost. They are cutthroats, thieves, assassins, murderers that want to do their dark trades far out of the reach of the forces of like law and order, or groups like the Zakarum who might be able to put a stop to this .
