Could also style it after the Winchester mansion that was built as the widow started feeling as if her family's wealth via gun manufacturing and genocide was creating massive angry mobs of spirits (so the mansion was built like a maze to confuse them, I visited as a kid and it's creepy as fuck). So there could be a part in which the players help angry spirits (former native inhabitants, mine workers left to die, etc) tear down the mansion and take the family to Hell.
