NannyMUD

NannyMUD is a fantasy-themed multiplayer text adventure founded in April 1990 by "Mats" and hosted by Lysator, an academic computer society at Linköping University in Sweden that also hosts Fredrik Ekman's Unofficial Home Page of Eamon Games. The MUD offers a large and complex world for players to explore and includes some Eamon-like features including an "Adventurer's Guild".
