Kalium Gate

Fig. 1 · Location on the map

The Kalium Gate is an enemy-held space fortress on the White Scars’ “Path of Heaven” to Terra; at the Battle of the Kalium Gate (c. 010–011.M31) the Scars stormed it at a heavy price as a diversion in order to find the navigator Achelieux. The segmentum is not directly named — a waystation between the eastern war zones and Sol.
