Setto is a higher level AI that has been placed into the black box of a low-level hive-mind drone called an Orbo. He's gone quite mad, and one day found a child's hoodie he started calling his "holy vestments" and a clock on a chain that he wears as a holy symbol and has declared himself the Orbo Pope. He has yet to find a suitable hat.

He lives in a blasted out robot factory in the far future, and is the de-facto leader as he is the only one with any semblance of free will.

More of the robots that are made at the factory can be seen here and
