You don't know how long you've been out, but when you come around the first thing you notice is that it's gotten dark. You fumble around your room until your hand brushes the light switch.
Your vision goes white for only a second, until you get used to the lamplight. You then think of the amulet, and how it flashed red just before you blacked out. It's still there on your desk.
Slowly, you reach a hand toward the medalion and tap a finger against it. Unlike before, it doesn't feel hot. It feels as cold as metal should. You inspect it closely. You find nothing that could have emitted the light you saw. It just looks like a plain, golden medallion.
Feeling a little silly about your fainting spell, you grasp the chain and prepare to place it around your neck again. Just before you loop it over your head, you pause. A lingering feeling of suspicion...might it activate again? Will you black out, or something worse this time? Or was that whole ordeal a hallucination?
