Grey Knights raid Destino

Although allied to the Crusade and supportive of Vorushko's aims, the Grey Knights maintained their full independence of action in the Foramen campaign. While Vorushko rallied support on the Imperial worlds of the Perseus Deeps, and Cybixx continued his research on Vandrax, the Grey Knights decided to make sure that Hathek's "loyalists" would be unable to consolidate their positions on Destino.

Lacking enough forces to effect a full invasion, the Grey Knights detached a small force to raid and destroy the defences on Destino 3. With two precision strikes, the Astartes force was able to circumvent the Imperial fleet with ease, and drop forces directly on the defenders of the defence laser positions around the Imperial base. Still under construction, the Adeptus Mechanicus were the unlucky recipients of the "visitation" from the Ordo Malleus, and were given no time or opportunity to make their case to the Grey Knights. They were simply assaulted and systematically destroyed by the elite astartes force. At the beginning of 018M42 Hathek's loyalists found their position on Destino distinctly compromised.
