No idea what a tiefling is, but hey. I've seen plenty in my time. Met all sorts, too. Since you mentioned no glowing hands, I'll just assume he's not my guy.
Hey, what's a story without some twists? And mine's been mind-crushing for a while now, so I wouldn't be surprised if it was just me attracting all this shit. Just need to find a place to sit down with a mug of ale and a few folks for a game of Wicked Grace, and I'll make do.
I might be clever, but the guys I mentioned would probably have figured out the magic boxes by now if they were around, too. Or, Sparkler would have been loud and cranky enough that you'd have noticed all his silks, first. He doesn't exactly keep quiet when he's put out.
Er. Just for reference, Sparkler's a human, the one of the party I haven't brought up yet. But since there hasn't been a hint of him vocally or on this weird... tablet thing.
