The shadow of death has fallen on the peaceful kingdom of Gurlion. The forces of Darkness, penetrating from the Lower World, have taken possession of the soul of King Arvor and are planting the cult of their cruel gods among the inhabitants of the kingdom. The only ones who can save the country are the three daughters of Desmond Scorpi, Count of Verset, twin sisters Sabina, Tamara and Drusilla, owners of the Power of Good . Knowing this, the traitor Merven, subordinate to a demon from the Lower World, kidnaps them and throws them into the depths of the underworld. The Forces of Darkness are triumphant; they do not yet know that among the terrible monsters inhabiting the underground kingdom, there lives one who is in no way inferior to them in strength.
