In Campaign Mode, it can only be entered after activating both Shadow Locks in The Unknown Depths and The Storm Halls. It is a dark plane filled with Shadow Vermin, Sand Dwellers and Wraiths. Inside, the Horadrim once hid the body of Zoltun Kulle that they could not destroy. Visually, it is a generic Act II ruins dungeon, except for it is very dark, lit with dim red light, and constantly swept by black, sandstorm-like torrents of smoke. There are two portals inside, the second opening immediately after the player picks up the body.
