The Official Prequel Comic Series to Galactic Battlefield
Red Horizon explores the early centuries of the Tempered Sol timeline, beginning in 2061 as humanity struggles to turn exploration into permanent settlement. Mars, Callisto, Ceres and the growing Outer Colonies are not yet distant legends — they are dangerous places built by ordinary people who know that one failed reactor, one lost convoy or one bad decision can kill an entire settlement.
Five books are planned in the Red Horizon series. Book 1 is available free — the entry point to the universe. These are the stories that eventually become history, with The Thirteenth System novels and Galactic Battlefield expanding the same canon in development now.
