Medievia, also nicknamed Medthievia, is a MUD created in 1992. Medievia was popular in the mid-1990s, having over 100 players at off-peak hours. Some controversy exists regarding Medievia's relationship to DikuMUD, and whether it is bound by the DikuMUD license as a derivative work. Authors of DikuMUD, as well as former staff of Medievia and independent programmers, have said that it is and thus violates the license agreement.
