Moria is a roguelike computer game based heavily on J. R. R. Tolkien's novel The Lord of the Rings. The game's objective is to kill a Balrog, presumably Durin's Bane, deep within the Mines of Moria. A later port of Moria called Umoria (UNIX Moria) inspired the Angband roguelike game. This game influenced the preliminary design of Blizzard Entertainment's Diablo.
