Frostgrave

Frostgrave is an icy death world orbiting Karka's Sun. It is the furthest inhabited world from its parent star, and the nearest outpost to the system's Mandeville point. In the system's economy, Frostgrave serves as an outpost world. Karkan and Mechanicus sub-light vessels ferry noctilith shipments from Oxidia and Karkason to Frostgrave, where the planet's fortified city-spires and low gravity allow warp-capable cargo vessels from out-system to quickly dock in low orbit and fill their holds. This prevents the out-system ships from making the time-consuming journey into and out of the heavy Karkan gravity well, and keeps Karkan coffers filled.
