Dylan is sent on a mission by a triumvir, but is not well informed of the danger he faces. After a haphazard reentry from slipstream, the Andromeda is captured by a gravity field projected from the moon that is the target of their mission. Dylan discovers that the moon is the base of Kroton, a half-human, half-android genius that created the Magog world-ship. Dylan attempts to take out Kroton along with the new weapon he has developed.
The Commonwealth spanned three galaxies and a myriad of cultures. Dylan Hunt, captain of the star ship Andromeda, was frozen in time and awoke three centuries later to find the Commonwealth had fallen.
To fight back the chaos among the stars, Hunt must use the Andromeda to restore the Commonwealth and bring unity to the galaxy once again. He recruits a mercenary, Tyr Anasazi, and the crew of the Eureka Maru: Captain Beka Valentine, Engineer Seamus Harper, Physicist Rev Bem, and Medical Officer Trance Gemini.
After discovering the Spirit of the Abyss and its powerful weapon, the Magog Worldship, the need for the Commonwealth is greater than ever. 50 member worlds are finally recruited, and the reconstruction of the Commonwealth is finally truly underway.
