Feior

Feior is a powerful sorcerer and warlord, who serves as the main villain in the Fighting Fantasy gamebook Black Vein Prophecy, unique among the series gamebooks because of its setting and the deep background of its playable character. Feior is the twin brother of the playable character Maior, and like his brother, he was put into a magical slumber by his father, the vile tyrant Bezenvial so that one of them would take back his endangered throne upon awaking. While Maior awakes amnsesiac and slowly gets purged of his evil, Feior awoke fully conscient of his mission and raises a powerful enemy to take over the Isles of Dawn. Feior was very close to fullfiil his goal but his armies, and later himself, were defeated by Maior and he was taken prisoner. Thus, Feior is one of the very few Fighting Fantasy villains not to be slain after being defeated.
