Sludge Fen

The Sludge Fen is an oil field the northeast corner of the Barrens. Occupied by the Venture Trading Company for their oil refining projects, the fen is one of the two refineries that can be visited in game, the other being in Stranglethorn Vale. This is a dangerous area to adventure in, as the cowardly Venture Co. employees will rush for help if they are attacked.
