Fig. 1 · Location on the map

Maerdan is a colony world on the edge of the Segmentum Solar; at the Ruin of Maerdan (008.M31) more than 200 Titans met — one of the largest early Titan battles: the loyalist Legio Gryphonicus, Metalica and Destructor against the traitor Legio Mortis, Argentum and Vulturum. The world was cleft apart, and no one achieved victory.
