Is There a Batman?

When the lid of the oak chest is opened, a large humanoid creature with the head and wings of a bat will be instantly teleported into the room. This Batman rags a claw through Magnus and as he does, Magnus explodes into pixels. I'll cast fireball at the bat to kill it. Does that mean... maybe he's friendly? Wait, no, he did just kill me. It just killed you. You can tell me to talk to him. The bat... The devisciated you might be our friend. And then he points to the buffet and he says, Yes, that's perfectly under. Can I get down? Yeah, no! Wait! Hold on.
