If you are a Shadow Lord (*ominous echo into the abyss in place of SLord population*), please remember that The Vault is wide open for the use of any of our Tribe. It has several rooms, one of which is sadly, @chown'd to Avery, so that means there is one guest room open. It is above a working Auto Body shop, and the top floor is suitable for training and the rougher aspects of asking an enemy a question.
The main room is #618.
