The Halls of Agony is a dungeon area of Diablo III that was first seen in the Blizzcon 2010 demo. It is presumably part of [Act I], but the name is likely subject to change. The area served as the starting location for players in the [PvM] demo. Based on the quest information provided in the demo, it is part of King Leoric's dungeon. The Halls of Agony were linked to another area: the [Highlands Passage].
