Creativity. Fuck.

Please send me a conveniently available werewolf.
"I've had an idea," says Loki. "It's not going to be particularly pleasant. If it works you get to live. If you try to hurt this wolf or run off I will stop you. Is that clear?"
"I'm making an exception to the voluntary turning rule because these people here are inhibited in their ability to volunteer things," Loki's illusion says to the wolf. "Please go ahead and gently attempt to turn that orc." She picks one and points.
Boy isn't Thauron going to feel like a moron if he left her transmissible free will.
"They're orcs. The Enemy's principal troops. They brought me a message from Thauron - nothing to do with you guys, it was about something else - and now I am trying to figure out how I can avoid having to kill them. If I let them go without figuring something out they'll spend the rest of their lives trying to kill Quendi."
"Thauron must have expected it, or he wouldn't have sent them. I used to have a way to make it so I wouldn't have to kill orcs I found, but he cut it off, doesn't work any more. They've been very cooperative so far, but that's because they're afraid of me; they are actually incapable of changing allegiances - unless what you just did worked."
