Black Warrens is a Deathtrap level.
Description
The archeologists dedicated to the study of the Deathtrap Strongholds have long argued over the question of whether this haunted place was once a factory dedicated to the manufacturing of the occult mechanisms or a place of worship to a long-forgotten machine god. We might never know for sure, but the obsidian platforms, the cast-iron girdles, the chaotic maze of staircases and the gloomy chasms definitely have an air of grim sanctity - a sanctitiy that will be desecrated every time the Chaos Portals disgorge their shrieking hordes onto the black, empty floors.
