he was a secret. he was kept as one. he did not know the rest of the galaxy existed. he was lonely, one day he escaped from god knows where! suddenly he saw a movement that wasn't him...he said "Oh my gosh is that part of me or what?! I thought I was the only living creature! Yet here is a movement that's not my own!" He looked down at himself and realised he was not human. He was a lonely floating brain cell that used to be the only ewok left in the UNIVERSE! but then he died so there were no ewoks left.
