Quest for the Mighty Sword

Quest for the Mighty Sword aka Ator 4, and Trollis the fourth and final film in the Ator film series, although it is regarded as the third film by the series creator, Joe DAmato, who disowned AtorIron Warrior which was the only film in the series not directed by DAmato.

Once upon a time a god gave a mighty sword to the king of Aquiles to bring justice to his people. Now he wants it back but the king rather gives his life than the sword. Goddess Dehamira, who spoke for him, is being taken all her privileges and banned in a circle of fire, until a human arrives whos strong enough to free her. When prince Ator becomes 18, he gets the sword from the mean sorcerer gnome Grindl, to free Dehamira and his people. On his journey he has to fight against dragons and other fantastic figures.
