On the beautiful planet called Islands, the colony's Artificial Intelligence failed generations before, and with all contact to the Home Government cut off, a hostile feudal society arose in which men were used only for manual labor and sex. When Tom Hark and his crew arrive, they are immediately imprisoned and only through the princess Sellia can they be rescued. .
