HERE is a video of the final battle at the end of Wizards and Warriors Camp, with some glimpses of Michael and Chewy (it is a four minute video; Chewy and Michael and about one minute+ in). There is a lich, a man with a witches heart in a box, zombies (that would be Chewy among them) and Anubis.
Chewy will be writing an update to this post with his description of the day.
Meanwhile, here is a picture of him when made up.
Michael had a great time at the camp and cannot wait until next year!
