The Writhing Haunt is an area located in the central part of the Western Plaguelands, just east of the Ruins of Andorhal. Originally the area was a life-sustaining farm, but it has since been overrun by the vile Scourge. In their quest to destroy the living, they have placed a large cauldron in the middle of the field which constantly spews disease-filled vapors into the air. The cauldron itself is protected by Cauldron Lord Razarch, Rotting Ghouls, Freezing Ghouls, and Fetid Zombies.
You can find Mulgris Deepriver, a quest giving NPC, hidden inside a house at the Writhing Haunt.

The Haunt now appears empty, devoid of all its former Scourge presence, and largely regrown. During the Alliance quest-line, Alliance farmers ventured here to farm for food, only to be attacked by Forsaken attackers and raised as undead. Those that survived joined the Alliance to fight the Forsaken for Andorhal. Thus, abomination Gory is the last remaining one on the farm.
