Circle of Heroes

Vastia is in a state of war. Led by the evil Paksahara, whose command of the Shifting Fortress gives her nearly unstoppable power, an army of undead animals is wreaking havoc on the queendom. With human magic still gone, it's up to the three prophesized familiars-- Aldwyn, Skylar, and Gilbert -- to capture the fortress and bring Paksahara down.
