Malvolion's inhabitants discovered a Tyranid beacon on their planet and sent for aid from the Imperial Guard, who arrived in the form of the 15th Mordian Iron Guard, several Phyrus regiments (including the 4th) and a Paladian tank regiment. They could not, however, save the planet.
Even as the evacuation was underway, a sudden outbreak of Genestealers and Lictors sent the planet into a panic before, only minutes later, a full scale invasion was taking place. Even the belated intervention of the Lamenters Space Marines was not nearly enough to stop the plague, and the barren world now stands as yet another symbol of the Great Devourer and its mighty fleets.
