OK, this is still sort of vague, even in my storyline, but it's giving me a headache 
My characters need to trap a fairy - a malicious, semi-intelligent fairy, sort of like a boogie-man type. HOW do two mortals trap something like that? What could you trap it in or with? It's a shape shifter, so they can't just tie it up or something with iron chains. Boo. HELP? It's repelled by iron, but not incapacitated by it. Rather like insect repellent I guess.
Iron is the typical recourse with Fae, so I'm at a bit of a loss. Ideas?
