Triplex Sector

The Triplex Sector is the Ultima Segmentum Eastern Fringe cube of the Triplex forges, the neighbourhood of Triplex Phall, Galatia, and Thule that once rivalled Mars at the edge of the map.

Night Lords hit the forges in the Thramas Crusade because they were arming Dorn; some priesthoods flipped, then the Lion arrived. Phall still stands in M41 with Legio Victorum and a habit of not sharing STCs with Mars.

The Triplex Sector still matters as the Fringe's remaining shipyard. Unofficial maps keep the Ultima parent and leave Phall a direct child of this row.
