I'm loving Ixi's and Fjolnir's zest for (un)life!
The Barrow King comes in a respectable third, for what I read as "grouchy old man" vibes that might clash and intertwine delightfully with our MC's friendly/energised teacher vibes.

Edit:
Ok, so I just had a thought. What if we get Bracht to animate our new skeletons and put them around the island, and then have visitors be drawn around ON AN UNDEAD POWERED VEHICLE THAT RUNS ON TRACKS! in some sort of cart?
There'll be security systems and fences and the like, of course. Probably won't need that big a team to oversee it either.
Just one dude might be enough, if we're worried about the returns we'd be seeing on this endevor.
