About: Despite his age, Kallen is the owner and manager of the decadent Ace’s Out Casino. This fledgling entrepreneur runs a tight ship, with the patrons of his casino leaving with less (clothing) than what they came in with. While Kallen prefers to watch things play out from afar, he cannot control his gambler’s spirit for too long and isn’t afraid to get involved when the stakes become high.
