Girth Loinhammer and the Quest for the Unsee Elixir

You are Girth Loinhammer, Dungeon Lord! It's a pretty sweet gig, with a gigantic trap-filled underground dungeon and a vast collection of torture devices with which to torment those who venture within your domain.

Or rather, it would be a pretty sweet gig if the people venturing within your domain weren't as keen on all that as you are: you have seen things that cannot be unseen.

...or can they?
