WoTMUD, the Wheel of Time MUD, is a classic-style Multi User Dungeon (MUD) based on the Wheel of Time book series by Robert Jordan. It has been online since 1993 and has evolved and grown enormously since its initial inception. It is the only Wheel of Time-themed MUD which was approved by Robert Jordan himself before he died and contains such an enormous array of detailed zones that many players whose introduction to the Wheel of Time series is through the game are already quite intimate with many details of the story before reading the books. Originally derived from the CircleMUD branch of the renowned DikuMud codebase, it has evolved so far at this point that it is no longer considered a true Diku/Circle code base but rather a branch derivative of its own.
