Chondax System

Fig. 1 · Location on the map

The Chondax system is a triple system of six worlds; Chondax itself is a dead world with a breathable atmosphere. In the Chondax campaign the White Scars (sent there immediately after the Triumph on Ullanor) were kept by Horus’s design far from the core and first learned of the Heresy from Dorn’s astropathic message.
