The Great Khan longhouse consists of 4 rooms. The main room is where Papa Khan, Regis and Karl sit at a dinning table. The first room to the right is Papa Khan's room, and the door is locked, requiring a 75 Lockpick skill to open. Next to Papa Khan's room is Karl's room. The opposite side of the building to Karl's room is the kitchen, which contains various food items.
