"West of Elysian Fields" tells the story of humanity lost to viruses that are destroying them and, in desperation, send a distress signal into space. This brings an alien race, the Tulxok, that enslaves them. The storyline revolves around humans regaining their freedom with the assistance of an alien alliance known as the Dominion, who had seeded Earth millions of years ago in their likeness. The protagonist of the story is Jake Lanier, a human who resides in the Harrisonburg settlement, established a century ago after the Great Fall. Jake lives with his father, Ted Lanier, who is a prominent leader of humans. Jake leads an army against the Tulxoks to drive them from Earth with the help of an alien he loves, Phendra, a Vennaren from the planet Venair. The Vennaren are an ancient race that is part of the Dominion of planets. While leading Phendra to safety, the Tulxoks capture him and make him a slave in Elysian Fields. Ezera, a Tulxok girl who does not agree with how her kind treats humans, helps him escape to join the human army and begin the great battle to save and retake Earth for humanity.
