Vance Theren - History: Educated at the Schola Progenium on Veneris, Vance Theren has faithfully served the Commissariat for the past sixty-five solar years.The most senior Commissar in the Orpheus Salient, Theren has presided over matters of military discipline since the first day of the salient's foundation. A veteran of many conflicts, Theren has served both on the ground alongside the Astra Militarum, and as a Fleet Commissar with the Imperial Navy, giving him valuable experience in a variety of theatres of war, and making him an ideal choice for such high authority.His oversight of all Astra Militarum and Imperial Navy activities within the salient is carried out through the means of thousands of lesser Commissars stationed aboard starships and deployed within Astra Militarum regiments.He was assigned to the Achilus Crusade from the outset and was attached as a liaison to General Mikal Curas' staff. A dutiful and honourable man, Theren does not suffer the wasteful use of the Emperor's armed forces, regarding the lives of the Emperor's servants as something not to be expended frivolously or rashly. Indeed, quite at odds with the archetypal image of the Commissar, Theren cares about the soldiers under his authority.This has caused him to clash with the generals under his jurisdiction on several occasions, even going so far as to veto the battle plans of General Derian Arkelius more than once, and having executed several senior Astra Militarum officers for negligence over the years of the Achilus Crusade.Further, he has reprimanded several of his subordinate Commissars for being overzealous in their punishments. The lives of the Emperor's servants are valuable and it is the responsibility of their leaders to ensure that the dutiful efforts of even the least of men are employed wisely, as Theren is swift to point out to his subordinates.In spite of this atypical outlook, Theren is a stern disciplinarian, having established a collection of penal companies in order to deal with those who step out of line, and commandeering a special battalion of veteran troops to serve as military police, as he has found that squads of exceptionally disciplined troops, unbound by regimental loyalty, make effective enforcers.Theren's respect for the lives of his troops became apparent to the other two members of the governing Triumvirate of the Orpheus Salient when he rewrote the defence plan for Treyan upon seeing General Arkelius had called for over one million Imperial Guardsmen to be sacrificed as bait to bring the Tyranids of Hive Fleet Dagon into a specified kill zone.Part of the Achilus Crusade from the very start, Theren served closely with General Curas, and he held the general in high regard almost from the outset.The death of General Curas at the hands of the Tyranids hit Theren hard. While they could not be considered friends, the two men had a mutual respect for one another and General Curas would often take Theren into his confidence about private command matters. Curas' death was an emotional blow to Theren, though his stern demeanour will not allow his acute sense of loss to show.In the wake of Curas' death, Theren was the source of the plan designed to replace Curas in command of the Orpheus Salient without news of his death becoming public in such a way that it would demoralise the crusaders.Theren's plan, later called the "Great Deception," was to inform the other salient commanders of General Curas' death at the hands of the Tyranids, but with communication blackouts he knew that it could take Terran years for such a message to be received and years beyond that for a response to be sent back.During this period no one beyond Theren, the Arkelius siblings and the crusade's High Command was to know of the death of General Curas until a replacement had been sent. In the meantime, and to keep the discipline and morale of the Orpheus Salient at workable levels, Theren proposed that a "Triumvirate" be formed to command the salient.General Arkelius would be in command of all ground operations, Admiral Arkelius would be in command of all naval actions, and Lord Commissar Theren would play the mediator, as well as having final say over any disagreements that cropped up.Now commanding from the flagship of Battlegroup Cerberus, Lord Commissar Theren is able to effectively deceive the rest of the ranking members of the Astra Militarum and Imperial Navy by combining his authority with that of either one of the Arkelius siblings. The word of a lord commissar backed up by either a lord admiral or a general is something no lower-ranking officer would dare question.As the orchestrator of the Great Deception, Lord Commissar Theren is constantly on the lookout for signs that one of the two Arkelius siblings is plotting his downfall.Without his iron discipline keeping the rank and file in line, the Orpheus Salient would be lost. His relationship with the Deathwatch is strong since, as a commissar, he always appreciates when a walking morale booster shows up on the field of battle.
