"A Legacy of Revenants" is the third book in the hard sci-fi Carina Sagittarium series, set in the aftermath of a devastating galactic war that destroyed humanity's great space stations. The story follows multiple converging storylines: The massive alien vessel Kingslayer, carrying thousands of human refugees, mysteriously vanishes using advanced quantum technology, leaving only witnesses to its sudden disappearance. On Terra, a shadowy figure named Piotr crashes in a forest and begins building a new empire from the ruins of the old order, forging alliances with Terra's genetically-modified inhabitants who have evolved over millennia. Simultaneously, the enigmatic Dark Lady abandons her role as hidden puppet master, taking physical form as "Nyx" and uniting scattered resistance groups into something called the Alliance of Ravens. All of these threads converge as the groups face a new cosmic-scale threat—something massive approaching the Solar System from the direction of Procyon, consuming matter as it travels. The book explores themes of consciousness evolution, the transformation of artificial beings into something more human, and how civilizations rebuild after collapse.
