In a long forgotten era, the end is near for humans. Is in this despair where a small town exists, sheltered from radiation and demons inside a profound cave. Long thought as uninhabited, an evil appears at the cave, causing terror and despair.
A long forgotten hero, Khar, appears and confronts the evil. Battle unfolds, but it's too much of a challenge to the old hero. With the help of his daughter Mao and his son-in-law, Oscar, they drive the evil away. But Khar finds himself under a curse caused by the evil. So, to lift its curse, he must seek the evil again, and vanquish it once and for all.
Khar, Mao and Oscar then set foot to the inner places of the cave.
Taking a regular RPG as a base, there is not THAT much difference at the overall systems. Though here is a list of special features systems have (specially battle).
