[Devin stops when Fai does, even though he could drag the other man along easily if he wanted to. He doesn't blame him for the confusion, although it's less bizarre for Devin than one might expect. Most vampires in his world could do that, unless they were killed in certain definitive ways.]

You'd think it would be, but apparently it's not. [He reaches under his shirt and pulls out a simply-set gem on a cord around his neck.] Everyone brought here gets one of these; they call them soul gems. [The vampire's tone is dry. He doesn't actually have a soul in his body, at current.] You'll have a bit of jewelry on you somewhere that you didn't have before - don't lose it. Anyway, these things tie us here, and keep us from remaining permanently deceased. Or more permanently deceased, in my case. [Having no heartbeat made such topics amusing, occasionally.] It's all very powerful magic.
