Haven

Haven is a place in The Pitt which is added to Fallout 3 in the DLC The Pitt. It is the home of Ashur and his family from where he rules the Pitt. The building's exterior is almost certainly meant to represent the Fallout world's version of the University of Pittsburgh's Cathedral of Learning.

Accessed by traveling through Uptown, the Haven is guarded by many of the Pitt's Raiders. From here, Ashur organizes his army and maintains his city while his wife Sandra tests their daughter Marie to discover a cure to help the denizens of the city.

Depending on the Lone Wanderer's actions, the Haven may either become the site of a failed revolution by the Pitt Slaves as they try but fail to gain control of The Pitt, or a massive firefight as the player joins in the revolution. If the player sides with Ashur, it presumably remains the center of the Pitt's rudimentary government. Should the player side with Wernher and kidnap Marie, Haven becomes locked (requiring a key to gain entrance) and is surrounded by Trogs. When Haven is locked after siding with Wernher, player can regain access to Haven by killing Wernher after Free Labor quest. This action will cause 120 points karma loss. If Wernher can be killed at the Pitt Train Yard, (he sometimes gets stuck there) the slaves in downtown do not turn into enemies against the player.
