The Algol star system holds three worlds: Palma, green and temperate; Motavia, harsh and arid; and Dezoris, frozen and remote. For generations all three fell under the rule of King Lassic — once a just ruler who became something far worse after a series of political changes that no one has fully explained. Pockets of resistance form but accomplish nothing against his forces. When her brother Nero, a rebel, is killed by Lassic's soldiers, Alis Landale makes a choice: she will finish what he could not. Recruiting the warrior Odin, the wizard Noah, and an unusual catlike creature named Myau, she builds a party capable of crossing all three planets of the Algol system. The journey is long and the opposition formidable, but Lassic is eventually confronted and defeated. A disembodied voice then directs the party to Motavia — where something far more dangerous than Lassic has been waiting: Dark Falz, whose defeat finally returns peace to the Algol system.
