Instead of Joseph, the player now takes on the role of Maia, Queen of Halassar, who is the goddess Laharah reborn, and can transform herself into a variety of "summonable" creatures.

Halassar, a province in the Empire of Galdyr, distant from the kingdoms of Medeva and Orenia, was foretold as the birthplace of the Goddess Laharah Reborn.

While reclaiming the Book of Prophets from the Halassar Palace traitor Dama Sivora, Maia activates a rune stone embedded in the pirate island stronghold of Prince Neru, on the Isle of Teomura, gaining the ability to transform into one of the 4 Summons.

They hope to use a flying vessel which belongs to the legendary Morbazan who lives in Munari City, home to an aquatic race that worship many gods.

Maia finds herself in a place called the Wheel of the Perduellion, controlled by a race who define themselves by a complicated system of Masks and are intent on slaying all of their gods.

Once Maia has freed all of her party, they must fight the Perduellion's new tyrant ruler Ushandul and travel to the stronghold of Sharangir to control his tower and therefore defeat the powerful Khargathalan.
