The Magus were legendary magic casters/warriors, able to cast spells and wield powerful magical weapons. They were the guardians of magic in Attlain but were cast out and feared for their power. Marcus Gideon was trained by The Last Magus, destined to restore the dignity of the order.

After graduating from the Basilon Magical Academy, Gideon sets off for his master's homeland. Plodoro was an isolated city in the far north of the Skjem-Tur mountains. Surrounded by giants and blanketed in an endless winter, Gideon traveled to the far-flung region to fulfill a final request of his master and return a sacred weapon to his people. He must finish this task to return to his true love, Wren.

The First Princess of Attlain fell in love with Gideon during their time at Basilon. Now, to win her parents' approval, Gideon must win the Helios Arcanum Magical Arts Festival. This celebration showcases the best magic casters in Attlain, and Gideon is the first Magus to compete in over a hundred years. As he fights for his life and reputation, a dark shadow looms over him as the Ulbrecht Domo-the Shadow Lord of Ishtar-has other plans for The Last Magus.
