I first encountered the concept of Hell as a bureaucracy from Piers Anthony. His Incarnations of Immortality series is another that Helena would recommend.
Incognito: So, are you Satan?
Baalberith: Of course not. I’m just a minor demon.
There are lots of us; there have to be, because we deal with the paperwork.
And Hell is a bureaucracy.
Incognito: Makes sense.
Baalberith: Follow me.
