This mansion was one among many in the formerly exclusive neighborhood of Esplanade. Now although a shell of its former self, its former grandeur is still plainly evident. In October, 2287 this dwelling was utilized by the Gunners as a forward operation base for their retrieval mission into HalluciGen, Inc. The hallway upstairs was turned into a sleeping area while the dining room and foyer were fortified against attack. As it turned out, the worst danger came from themselves: A member of the raid who managed to retreat from HalluciGen died of blood loss while trying to patch himself on the sleeping bag in the kitchen.
The main entryway leads into a grand, marbled home. Upon entry the door leads directly to the den/foyer. To the east is the former dining room, now turned into a Gunner fortification. To the west is the stairway to the second floor, at the top of the stairs is a hallway turned sleeping quarters. Past this a bookcase blocks the door to the rest of the building.
