Castel Nova Insurrection

The flames of rebellion and treachery engulf the Civilised world of Castel Nova, the world's Planetary Governor and by affect it's Astra Militarum and Imperial Navy elements also, succumb to the putrid taint of Nurgle. Responding to the cries of still loyal elements upon the planet, the Ordo Malleus of the Emperor's Most Holy Inquisition lead a coalition of Imperial forces to the world, consisting of multiple Regiments of the Imperial Guard, elements from the nearby Battlefleet Hextilia, Legio Obcasus of the Collegia Titanica and forces of the Adeptus Astartes, consisting of the Void Krakens 2nd and 4th Companies, and the Iron Serpents 3rd Company.

After gruelling campaigns of attrition and rapid dominance as entire hive cities were wreathed in fire as the corruption of Nurgle was burnt away with zealous and wrathful intent, renegade forces were quickly routed and purged by Imperial forces, the Iron Serpents taking lead of the Astartes ground elements, shattering Renegade strategic locations, some of which being the vast batteries of Earthshaker Cannons and Hydra platforms that were stalling the siege of the planetary Capital of Hive Noctalis and the collapsing of many of the labyrinthine networks of tunnels leading to and fro in the Underhive below to the wastes beyond the Hive walls. While in the void the Void Krakens shifted their focus to the Renegade navy in orbit and the heretic base upon the jungle moon of Tsi'van. Providing support for Battlefleet Hextilia, the Kraken fleet destroyed many of the smaller classification of Renegade ships and boarding the few Capital-class vessels in their possession, meeting little resistance that could pose a true threat to the Emperor's finest onboard. During the preparation for the assault of the moon of Tsi'van, the Battle-Barge *Silent Sunder* was voxed by Inquisitor Daleitis himself, stating the cessation of the ground assault upon the moon, declaring Tsi'van to be subject to Exterminartus and ordered the *Silent Sunder* to unleash a Virus-Bomb upon it and igniting the flammable refuge of gaseous sludge that remained of the moon's ecosystem and sentient occupants, effectively transforming the moon's atmosphere into a horrific firestorm of Imperial wrath.

After the eradication of the Renegade forces upon the moon and the subsiding of the firestorms, the Void Krakens were once more contacted by Inquisitor Daleitis, now 'requesting' a force of Marines to venture with him and his own retinue to the now blistered and blacked fortress that once held the heretical forces upon the ruined surface. What came to pass within the fortress is unknown, as the Battle-Brothers that accompanied the Inquisitor were subject to mind cleansing before their return. It is theorised that something abhorrent in nature resided within the fortress' heart, as two Void Krakens fell while in the Inquisitor's care. At scrutinization Inquisitor Daleitis went so far as to swiftly ignore and proclaim his greater authority at the heated questions posed to him of their fate by Lord Leviathan Talvin Bekalis. When returned by their brothers it was noted that their armour was covered in gore and putrid sludge, while marred with great rends that seemed to look physically aged and rusted, with the Chapter's Librarium stating the wounds reeked of warp taint. It is known that the Ordo Malleus Inquisitor returned from the moon's surface with many of his retinue absent and within his possession some form of large stone relic of unknown origin, though all else that transpired upon Tsi'van was seemingly to be forever veiled in mystery and the Inquisitorial seal.
