You were doing whatever in the earth world, where, of course, you were born and raised. Though you black out, awakening in the sand, near a rock, you're only wearing undergarments that are made of weak leather, barely covering anything.

You look at your wrist, seeing a crystal like item embedded in your skin, when you hear a noise, out of instinctual reaction you sit up a little, hiding slightly behind the rock when you see; a Giant crocodile like creature that looks like it should he extinct with a woman riding on it.
