Masca: The Tale of the Great Mage of Hessed

The Devil's Castle is a dark and somber place, until the good-hearted apprentice Asarella stumbles into this abode on a goodwill mission, against the wishes of her master, the Arch-Mage, Eliwho. Things sour quickly, and soon Asarella is bound in a blood pact with The Devil. Little does she know that the mage harbors a secret love for her, which will only complicate her training to prepare her for the apocalyptic battle to come, and which sets up the most unusual love triangle of any place or time.
