In all my time working the Faire, I've learned a lot of things about customers. Here's one of those nuggets of wisdom: customers love stuff that glows! It doesn't matter what it is - you could take a broken chair leg and make it glow, and every child will come from miles around to get one!
So, <name>, I need glowing scorpid blood. You can find it from the scorpids of Sillithus, or the Blasted Lands, or the Burning Steppes.
