Hades' Vault

Hade's Vault is actually an armoury where Hades keeps all of his magical artifacts, antiques, treasures and weapons. It is first introduced and seen in Skin Game.

Skin Game
In Skin Game, Nicodemus Archleone plans to break into the vault to obtain a very powerful weapon - the leaf shaped knife. He is, however, set up by Mab, Hades and Marcone to make sure that Dresden is able to secure most of the weapons before Nicodemus.
