Elisa Maza: Oberon wasn't too thrilled when I pulled my piece. Too bad I was only bluffing, I've been out of bullets for weeks. Of course, for him I guess they'd have to be silver bullets.
Princess Katherine: No. Silver be for vampires and weres. For the Children, cold iron will do.
Elisa Maza: Iron?
Guardian: Oberon's children have always been vulnerable to it. Aye and Oberon himself as well.
Elisa Maza: [looking at her gun] This is steel alloy with a little iron. That's why Oberon pulled back when I drew on him!
Guardian: Yes! Recall that when the Magus faced the Weird Sisters, he bound them by iron chains.
Princess Katherine: Those chains might still be here, somewhere.
Guardian: And we have a forge with which to shape them into a weapon!
Elisa Maza: [Gives gun to Tom] Every little bit helps. The only question is, what kind of weapon?
