Dungeon Master: Theron's Quest (1992)

Terrifyingly brutal beasts! Monstrous mazes! Treacherous pits of evil! The adventure of a lifetime is here....Theron's Quest!! The Monastery at Ya-Brodin has fallen to the Cult of Deaths and the Brotherhood of Enlightenment, the true keepers of Magic, have been slaughtered. The Seven Great Treasures now lie in the hands of foul beings who will stop at nothing to hold onto their massive powers. But Theron, with a courage beyond belief, has decided to seek out the Cult of Deaths and win back the Treasures. If he succeeds, he will become a High Lord. If not, the land will see eternal darkness.
