Voinium Shattering

The Voinium Shattering was an Imperial excoriation campaign conducted by the merciless and bellicose Emperor's Reapers Space Marine Chapter against the Aeldari Craftworld Wu'thule upon the Imperial world of Voinium III.

Background
In 019.M37, a corsair fleet from Cratfworld Wu'thule attacked the fortress world of Voinium III, home to a well-trained Astra Militarum regiment called the 'Imperator's Shield'. Despite holding back the Aeldari forces, they knew they could not hold out forever, therefore, the besieged world sent out an Astropathic distress signal requesting immediate assistance. Their prayers were answered in the form of the Emperor's Reapers, as they were the closest Space Marine Chapter to receive it. In response, they dispatched their Chief Librarian Aterius along with members of the Shroud Company and 2nd and 3rd Companies to help eliminate the xenos threat.

After three weeks of conflict, the Imperial forces discovered that the Aeldari were after a lost super weapon (a so-called 'Weapon of Vaul') capable of cracking planets to pieces. Determined to either capture or destroy the archaic weapon, the Shroud Company and 2nd Company intercepted the Aeldari strike force retrieving the weapon while the 3rd Company and the Imperator's Shield Regiment attacked the main Aeldari ground forces in attrition and trench warfare.

Despite taking casualties, Aterius slayed the leading Farseer in single combat, claiming the Farseer's weapon and Soulstone as trophies and destroyed the ancient weapon. Unfortunately, the destruction of the weapon started a chain reaction that would shatter the plant. After the Aeldari forces retreated into the webway, the Imperial forces rapidly evacuated the planet before it exploded spectacularly into millions of fragments.
