Triplex Phall

Fig. 1 · Location on the map

Triplex Phall is one of three linked forge worlds (with Triplex Galatia and Triplex Thule) on the far Eastern Fringe of the Segmentum Ultima; together they supplied almost all the loyalists’ shipyard capacity in the Ultima. After the Dark Angels destroyed Triplex Galatia, the loyalists handed Phall to Lion El’Jonson.
