Reclamation of Kathur - Curse of Unbelief: With the influx of power from the 13th Black Crusade and the focus of the imprisoned Daemon Prince, the will of Nurgle manifested upon Kathur as an outbreak of the Curse of Unbelief. At first, the Kathurian authorities were unresponsive: outbreaks of communicable disease were a common happenstance on a world where thousands of pilgrims transitted daily, and Kathur's only answer was to increase the patrols tasked with gathering and incinerating the dead.When reports started to filter back up of the dead rising and attacking the living, the Imperial Cult priests of Kathur recognised the dire peril amongst them, but by then it was already too late, as packs of living dead were spreading the infection almost exponentially.The Adeptus Arbites and elements of the Shrine World's Planetary Defense Force attempted to maintain order but failed, and Imperial control would collapse totally over the following twenty solar days. The planetary government of Kathur did manage to send an astropathic plea for help to Cadian High Command.Despite being hard-pressed on all fronts, the Cadian High Command saw a golden opportunity for a morale-boosting easy victory over the forces of the Archenemy, and immediately assembled a task force to reclaim Kathur.Appointing the very devout General Finneas Maggrig of the Astra Militarum as overall commander of the endeavour, the Cadian High Command planned a quick two-stage campaign: a battlegroup composed of immediately available forces would spearhead the Reclamation, with orders to secure Solthane, Kathur's capital city and its priceless Imperial shrines and relics.When the second, much larger Astra Militarum battlegroup arrived, Solthane would serve as a secure base and staging area for the scouring of the infected from the rest of the world. The first group was composed of several Astra Militarum regiments, including the Vednikan 12th and 303rd Rifles, the Uriah 25th Kiridian Irregulars, the Janus 3rd and 6th Skarran Rangers, the 40th Hadris Rift Armoured and the 88th Cadian Mechanised Infantry regiment.Their transports were escorted to Kathur by a small Imperial Navy detachment, composed of the Dominator-class Cruiser Depth of Fury, two Dauntless-class Light Cruisers and two squadrons of escorts. While modest, the battlegroup was judged of sufficient size to beat off any marauding Chaos vessel or opportunistic pirate pack, and deliver the troop transports safely to Kathur.Cadian High Command was pleasantly surprised when the spearhead group was reinforced by the Raven Guard strike cruiser Second Shadow carrying fifty Space Marines of the Raven Guard's 5th Company. Despite being hard-pressed across the Segmentum Obscurus, for the Raven Guard the reclamation of Kathur was a matter of honour: ten millennia before, Lord Admiral Kathur had fought alongside the XIXth Legion and assisted them during the dark days of the Horus Heresy.The sons of Corax intended to see Kathur's final resting place restored to the light of the Emperor. Shadow Captain Corvane Valar pledged his support, stating that he and his battle-brothers would assist with the liberation of Solthane and liberate the final resting place of Saint Kathur.
