Sarga the monster is an enhancement from a minotaur created for fun by Hardin's disciple. Disciple Lavidos has kidnapped the creature and infused it with the power of darkness, resulting in a bigger and stronger Minotaur with greater intellect. Amused by his success after Laum's creation, Lavidos has even created a circle of minions for Sarga. Now Sarga is on an indiscriminate killing rampage in Gludio to activate the magic circle made of monsters.
