Before you say anything stupid, let it be known that I thought this was a bad idea, too.
It doesn't take a genius to recognize that when some sketchy-looking dude reaches out to you with his sketchy-looking device and asks you to take on a sketchy-looking quest for a couple of days, you're definitely getting yourself into trouble. Heck, I could probably find any random rock around here and they'd have the sense to sit tight and do nothing.
Hey, you there. You want to take this crystal off my hands? No? Good for you. You've got common sense.
But this human - oh, this human of mine. Every day I find new reasons to be disappointed.
