Fig. 1 · Place on the map

Loyalist victory The Dreadwing scorches Triplex Galatia; the traitors flee Triplex Phall.

The Dark Angels destroyed the forge Triplex Galatia, which had inclined to the traitors, burning it with the Dreadwing. Terror at the wrath of Lion El’Jonson put to flight the traitors of neighbouring Triplex Phall, where the loyalist Mechanicum rose in revolt and handed the forge to the Lion — who spared it only in order to bleed its manufactoria dry for his campaign.
