Marvel

You always were a Marvel fan, the movies must have helped. You step into that door, and blink as you find yourself standing on top of Avenger's tower. A convenient place to start. To your surprise, Thor just walked right through you, bellowing at the top of his lungs - the gem must be making sure you couldn't be detected or interacted with unless you wished it.
So many ways to go...just have fun with the women, or become a hero and join the Avengers? With the gem, you could do almost anything you wanted...both were possible.
