In addition to being the King of Halloween, Jack is also a gatekeeper of sorts - keeping the forces of darkness from infiltrating unprepared worlds such as ours - except one day a year. A bit loony himself, but no one who wasn't could handle the job. He was elevated to the High Council recently, after it was discovered that the Friends might have access to our world thanks to Queen Narissa. As the only member of the heroes who has traveled between their world and ours, his knowledge makes him invaluable.
