Kakumaoh intends to attend. He'll probably use some accessories from "The Rape of Innocence - A Play" to make it look like he's wearing a costume if one of the rooms has a reasonably appropriate theme, although he may want some illusionary help to seem a more normal human height.

Seraph could provide an illusion spell.

Although he would probably demand a favour that he could call up later in return for it. (If he actually does call it up is another question entirely)

(Edit: Never mind. I'll be there.)
