Find The GM Event

Well, as the title say, a GM is gathering people into the event place which is a lot of small maps that will make a maze (more than 2 portals at every map that will teleport you to a random other map) and a GM is hiding in one randomly map of the maze, and the 1~5 first people to see him will win, then the GM announce the event has ended and everyone will teleport to the end event map (with the congratulation big thing in map looks like Lith Harbor and a clown npc).
