Ruin of Maedran
The battle saw the Imperial colony of Maedran on the edge of Segmentum Solar become savagely contested between the loyalists and traitors. Loyalist Titans of the Legio Gryphonicus, Legio Metalica, Legio Destructor clashed with the traitors of the Legio Mortis, Legio Argentum, and Legio Vulturum. One of the largest Titan battles of the early Heresy, more than 200 god-engines clashed as Maedran was reduced to ruin.
Ultimately heavy losses were incurred by both sides and neither combatant was able to claim true victory. In the aftermath, hatred between the Gryphonicus and Mortis only intensified.
