Mystic (also called MysticSG) is a level maker and a moderator on Total Jerkface. PhysX, Mystic, Bert, iDeViL360 and Udie are the only moderators on TJF currently. He joined Total Jerkface on September 19th, 2010 and was made a moderator on December 11th, 2011. His main purpose was to get rid of copied levels that would clog up the top rated list, as well as because Total Jerkface only had one moderator before. He does not moderate the forums or comments, he only moderates the game itself.
Mystic's first post as moderator was a post detailing his moderatorship. However, he changed his original post to "swag", presumably to show off his new found powers. As of now, Mystic rarely posts comments on the news posts.
He is also an administrator and bureaucrat on this wiki and sometimes considered the Father of the Wiki.
