A major supplier for the Sabbat Worlds Crusade, Orestes was attacked by a grand horde of Chaos Titans in 779.M41. The Forge's own force of God-Machines, the Legio Tempestus, was severely depleted through constant tithes to the Crusade, and stood no hope of holding off the hordes of Chaos. As luck would have it, the Legio Invicta was travelling past Orestes on their way to the Crusade main front after crushing a force of Eldar in the Beltran Cluster, and Lord Gearhart of Invicta came to the Forge's aid.
