Oh, your daemon was going to be slaaneshi? I Figured that you had figured out what I was doing to those guards so I upped the odds and made it a Great Unclean one. What did you think of Gelir? Was he slaaneshi enough?
He was a different kind of slaaneshi than what I was going to go for, though probably a little more traditional, and well done too, I thought he worked very well.
I had visions of something less decadent, with daemons torturing the guards in the shelter by doing violent carnal things to images of their loved ones, and committing other vile acts, trying to tempt the guards out to stop them/join them, or forcing them to watch the horror show and break them that way. It would be very dark though, and people would probably wonder if I have mental problems, so is probably best left out.
