Oh whatever! So you aren't in a complete void, and you do sense something! Big whoop!
The being seems bigger then you, and is moving away from you now at a speed much greater then you feel you could muster. That's about all you can tell about it, without trying to communicate with it. Unless...
You concentrate on expanding your awareness to include the conscioussness of this other being. You begin to hear it's thoughts. "Oh newbies! Just buzz off! I don't have TIME for this!" The being seems to speed up a little more.
