After 6000 years of peace the beautiful world of Ancardia is once more threatened by the forces of Chaos. Dark and sinister beings emerge from a huge dungeon complex hidden in a remote mountain range known as the Drakalor Chain. Ancient Domains of Mystery (ADOM for short) is a rogue-like game, which means, that it is a single-user game featuring the exploration of a dungeon complex. You control a fictional character described by race, class, attributes, skills and equipment. This fictional character is trying to achieve a specific goal and succeed in a difficult quest. To fulfill the quest you have to explore previously undiscovered tunnels and dungeons, fight hideous monsters, uncover long forgotten secrets and find treasures of all kind. During the game you explore dungeon levels, which are randomly generated each game. You might also encounter certain special levels, which present a particular challenge or are built around a certain theme.
