Interstellar Slug

The meteor comes down with a crash, leaving a little crater in the ground from the impact. The hunk of rock cools for some time, before a sickening crack echoes through the cool evening air as the meteorite splits in half, revealing a slimy, greenish interior space. Inside this space, you begin to stir. Six inches long, and roughly an inch and a half thick, you mostly resemble an Earthen slug, with one notable difference in appearance - your body glows faintly. Beyond your knowledge of your looks, your only current thought is to find a suitable host body to hide in; your higher brain functions rely on those of whatever host you have. Taking stock of the situation, you must decide if you are going to wait for a suitable host to come to you, or strike out on your own to find a body to control.
