Arka
Arka is a Cadian Astra Militarum General, who commands the Cadian 308th Regiment.[1a]
Unlike many Astra Militarum officers, the elderly General has refused rejuvenat treatments, preferring instead to live a natural lifespan in service to the Emperor. When the Second Tyrannic War began, Arka and his regiment were dispatched to aid Ichar IV, when it was invaded by Hive Fleet Kraken, but arrived after the world had already been saved by the Imperium. Though he could have returned back to Cadia, the General was eager for battle and his regiment fought the Imperium's enemies where they could, before answering the call to aid Styxia Prime. The Agri World was being threatened by a tendril of Hive Fleet Gorgon and Arka's regiment was among the Imperial forces that reached Styxia Prime as the Imperial Navy fought to destroy the Hive Fleet. Once on the world, Arka was made the overall commander of the Imperium's forces defending the Agri World and was also aided by the Titans of Legio Fortitudis. With these forces he quickly fortified the world's only city and began to the process of bringing Styxia Prime's population behind its fortified walls. It was at this time the Tyranids began to invade, but due to the efforts of the Imperial Navy only one of the tendril's Hive Ships was able to disgorge its brood before it died. Despite this though, the Tyranids would have overwhelmed the world, had it not been for the fortunate arrival of an Ultramarine strike force led by Ortan Cassius. This gladdened Arka, as he had become acquainted with the Master of Sanctity when his regiment arrived in the aftermath of Ichar IV's invasion, and they quickly worked together to formulate a plan to save Styxia Prime.[1a] Due to this, the Agri World was saved within weeks of the Ultramarines' arrival.[1b]
