In deep space there is the kingdom of Pangea, consisting of many worlds. It was founded by people from Earth, which had long ago turned into an ice ball after the only star in the system went out. Since the time of the first settlers, the kingdom, ruled by a just monarch, has grown stronger and stronger, despite the constant threat of invasion from the dark worlds of Attar, inhabited by nomads. The sudden death of the king, who died of an unknown disease, threatens a new war. But guarding the kingdom is its star fleet, commanded by Admiral Marceau. "Star Duke", as he is called in the Navy. As long as the Duke is alive, Pangea always has hope of victory. He is wise and strong, but even he does not know where the main danger to the kingdom lies.
