Bearded Devil
A creature that looks uncannily devilish appears to be trapped in a cell in the maze of corridors that is the Asmodean Knot. As it is the only living creature in a row of cells, and the only one we've encountered so far that can't attack us on first sight, we strike up a conversation. Skelra and I talk to it in infernal, pertty much confirming it is a devil, but we don't know exactly what it is, so we ask.
'I'm human. What are you?'
'Um, can you hand me the monster manual?'
'I, uh, I suppose so'.
'Right, I remember now. I'm a Barbazu.'
'Okay. And what's a Barbazu?'
'Cuts hair.'
'Thanks, Brennan.'
