A Game Master, or GM for short, is a person who is part of the staff that runs Grand Chase and act as officials. These GMs have special "powers" that regular players are unable to do such as banishment and the issuing of yellow and red cards. Certain GMs handle different parts of the game such as error reports. Most GMs usually do not communicate with the Grand Chase community but there are a few exceptions. The GM's Test of Endurance is one way to communicate and react with the GMs as they will actually play the game and PvP other players. Another way is through the Grand Chase forums where a GM may or may not respond to a forum post. A GM's in-game level will always be equal to or higher than the level limit at that current time.
A Game Master is stated to approve the image of a Guild Mark to determine whether the image is appropriate or not.
Past North American server GMsEdit
Note that most of the GMs in the list left when NAGC was transferred to KOG Games. (As of April of 2013)
