And Then There Was One
In a peek at the earlier history of Mobius, three cloaked figures are seen attempting to use magic to unlock knowledge of the events that occurred before the Day of Fury, but are unsuccessful. The three reveal themselves to be members of the Order of Ixis, namely: Agunus, master of earth; Nusgau, master of air; and Suguna, master of water. Deciding to partner up to obtain mastery over fire, the one element known to be beyond them all, they begin a race across land, sea, and air to reach the sun. After proving traitorous to one another in their respective environments, all three are pulled into the sun together. Later, at the court of Frederick Acorn, the king is distubred as the sorceror Ixis Naugus bursts in and offers his services.
