Barkus

Barkus is the stern, bureaucratic administrator of the Servant Allocation Center in Vault City in 2241. He is responsible for overseeing Servant work throughout the city, their assignments as well as acquisition. All the city's servants, old and new, come through his workplace and anyone seeking one has to go through him.

As many officials in the post-nuclear world, Barkus is a corrupt person. A hefty bribe allows the Chosen One to ask anything Servant-related and have it done swiftly. That is one of the ways in which Joshua can be freed by the Chosen One.
