The Immortal

The wizard Mordamir calls for help from deep below the labyrinth, attempting to communicate with a man named Dunric. The player, an elderly wizard, instead discovers the message and takes on the quest to rescue Mordamir–his mentor and master. While descending the levels of the labyrinth, a race of goblins and trolls at war are encountered, and the goblins allies with the player after sparing their king. The player also encounters many other hostile creatures within the labyrinth, including invisible Shades, flying lizards, Will-o'-the-wisps, flesh-eating slimes, huge man-eating worms, a giant spider and a water Norlac. The player is assisted along the way by the warrior Ulindor, Mordamir's servant and body guard as well as a mysterious merchant selling helpful potions and magical items.

Throughout the journey, the player sleeps on straw beds placed around the labyrinth, where dreams reveal an ancient civilization of peaceful dragons that once lived in the dungeon below. Visions are also seen of the walled-off ancient city of Erinoch, with its abundant fountains of youth and eternally young inhabitants. The dragons governed the city's source of fountain water from below, but the rulers of Erinoch planned a siege against the dragons for control of the enchanted water. Mordamir presented to the city's counsel a weapon he created to kill all the dragons, but was unable to use it for a reason unknown.

As the player nears the bottom of the labyrinth, he finds the trapped and dying Dunric, who explains Mordamir was never a prisoner, but instead kidnapped his daughter to lure him into the labyrinth as a trap. In a dream vision, it is revealed the entire race of dragons were wiped out by the city's army in a fierce battle, except for one that escaped the dungeon labyrinth and returned to the destroy the city and all its inhabitants. Mordamir, 1,000 years later, is the only survivor of his civilization, as is the one last dragon. In the end, the player is confronted by both the dragon and Mordamir in a final conflict.
