With the planet being digested around them and no hope of delaying the hive fleet any longer, the Imperial forces on Fratribusia pull out while their route of escape is still open, evacuating as much of strategic importance as possible. Military equipment and relics are all taken from their places of storage, while civilians of fighting age and build are forcibly removed from their families and inducted into the Astra Militarum to continue the fight on other planets. Billions of people, thousands of tons of equipment and stragglers from the Imperial forces are left to their fate with the xenos.
While the planet, it’s population and the regular tithe have all been lost to the Imperium of man, the hive fleet was held up for longer than expected, allowing more time for a build up of forces at the anchor world of Sanctum.
Battle group Constintinia has been formed from the remnants of the Imperial forces and been ordered to the planet of Chetis 4.
Chetis 4 is an arid world whose main off world tithe is focused on munitions, cotton fabrics and Imperial Guard regiments all of which are crucial to the on going war against the hive fleets of the Tyranids. In recent years, the planetary governor, a certain Cardinal-Astra Marcellus, has declared himself a facet of the God-Emperor of mankind himself, declaring war on the corruption of the Imperium as he sees it and stopping all tithe materials leaving while he builds his own crusading army.
While the vast majority of solblade strike forces are being pulled back to the anchor worlds, now their delaying missions have been completed, to help strengthen the lines, those involved in the Fratribusia conflict have been grouped together and reinforced with an extra division of Astra Militarum as Battle Group Contintinia tasked with bringing Chetis 4 back into the Imperial fold.
Upon reaching Chetis 4, Battle Group Contintinia has discovered that the problem is far more than a secessionist government and isn't confined to the single planet.
The first wave of attacks were lead by the 1st Division Astra Militarum (Hervictus 14th, 17th, 31st and the Fratibusia Free Engineers), supported by the Ossuary Brotherhood chapter of Astartes, the Order of the Fallen Angels, Adepeta Soroitas and House Steinschild of the Imperial Knights.
The Imperial Knights were deployed outside of the main invasion area to neutralise a repair and reequipment site used by traitor Knights, with the aim of knocking a potent threat out of the war early on.
The Ossuary Brotherhood was spread far thinner than planned when local, unsupported counter attacks from the forces of Chaos responded faster than anticipated but their heroic sacrifices meant the Imperial beach head has held, for the moment. Is a third of a company fallen in the opening gambit too high a price?
Even with a full scale invasion of the planet going on, the warbands roving Chetis, supposedly under the command of Cardinal-Astra Marcellus, have been unable to co-ordinate a full scale response and have been recorded fighting amongst themselves on at least three separate occasions.
Reported sightings of silver armoured Adeptus Astartes active on Chetis 4 are unsubstantiated and liable to lead to Inquisitional interest.
