Welcome to the Dark Horizons universe. The year is 2610, and the universe as you know it has changed. Mankind has conquered the galaxy; technological breakthroughs such as the Core Implant, the quantum electrino drive, and cybernetics have altered his way of life forever; and commerce with other species including Nomads, Cy-Gens, and the Valence -- has forever changed the way humanity defines itself. However, none of these changes has prepared mankind for the sudden appearance of the Irritus. Whether you participate in a Dark Horizons campaign as a player or as a Gamemaster (GM), your actions during the game will help shape mankind’s future. Whether for better or for worse is up to you.
