A Game Master who worked for NEXON INC.. He acted as GM from 2000 to 2004.
Although he was known to use many different characters as a GM character, Eldridge is the event character he used Eldridge (who had previously been a little used event character) the most, therefore players refer to this GM as Eldridge.
Trivia: He managed to serve as Game Master longer than any previous NexusTK GM had ever done before.
