The Halls of Agony is a dungeon area within 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.
Theme/Style
The Halls of Agony dungeon has a distinctive, blood-red color scheme with a host of fiery elements. Metal grates along the floor glow as if pulsing, red embers were burning below. Some grates occasionally spew flames that can harm both the hero and monsters (see the associated images below). Furnaces are also found that have been built into the walls of the dungeon and serve as Monster Generators. Overall, the dungeon has the feel of a torture chamber - with various torture devices (iron maidens, stretch racks, etc) strewn throughout.
