King Tut "Tell you what, that sounds like a pretty unfair proposition. I bet you are really bored in there, so how about we exchange some information and then we'll enter. At least we'll have died with the mystery solved."

I fill the demon in on what we know, the Knights, the attempted creation of the anti-knights, etc.

"Can you fill in any gaps in our knowledge? How did you get here, why were you brought here, and why did you end up staying here, doing nothing? Why are there so many undead, and disgusting, creatures here? And has anyone else been through here since the 'accident' or whatever happened that changed this place?"

I'll also take note of the pentagram and the demon's features, and describe them to Otto. Does he have any information at all? Is he pretty much happy hanging out, munching on food, and landscaping?  ¶ 4:54 PM
