They were openly gay right?
A flyer for a gay pride parade, and a map to show them how to get there. They're excited to make new friends, and spare me as a reward. Boom.
Or, if the weapons route is required, remember that modern technology would seem like magic to them. So , a jeep (whatever the one that can take the most beating is)with reenforced tires (if such a thing exists)And a sounds system to blast them with Confrontation by Otep while I run them down. I tell them the jeep is my magical chariot, and the music is produced by the tormented souls of those I have slain. If they don't surrender to that, then I got nothin'.
