Sebastian Yarrick - Sebastian Yarrick: Sebastian Yarrick, the "Hero of Hades Hive," is a commissar of the Officio Prefectus, famous for his involvement in the Second and Third Wars for Armageddon in the last century of the 41st Millennium. There he fought against the forces of the Ork Warlord Ghazghkull Mag Uruk Thraka.Yarrick was already old when the war began and was scheduled to retire on the day the Greenskins landed. He possessed an excellent history serving with Armageddon's Planetary Defence Forces and a reputation for unswerving loyalty to the Emperor.In his youth he had learned the Ork language from a human raider captured by the savage xenos and was one of the few recognised experts in the Imperium on Ork psychology and culture.Commissar Yarrick is a peerless Imperial hero. During the Second War for Armageddon, Yarrick held Hades Hive against the Ork hordes of Warlord Ghazghkull Thraka when the city's fall seemed inevitable.As the legends tell, it was this act of stoic defiance that would save the planet, for in Yarrick the Greenskin Warlord finally saw a worthy opponent -- a strategist of great cunning against whom he could test his brutal fury.Ghazghkull directed the majority of his forces towards Hades, and joined the battle himself, determined to crush the dauntless commissar beneath his heel. Yarrick rallied his defenders, and though the casualties were horrific, he managed to hold out until the Blood Angels Chapter of the Adeptus Astartes were able to outflank and destroy Ghazghkull's hordes.Furious at his defeat, the Warlord retreated from the system, ending the Second War for Armageddon. Yarrick's courage and tenacity were an inspiration to his followers, carrying them through hardships untold to eventual victory.It was during a brutal hand-to-hand duel with the hulking Warboss Ugulhard in the final battle for Hades Hive that Yarrick lost an arm. He took the Ork's head in return, replacing his severed limb with Ugulhard's own Power Klaw.When he lost an eye in a vicious fire fight, Yarrick ensured it was replaced with a powerful laser-bionic called the Bale Eye, playing to the Ork fear of his supposed "evil eye." Though his body is a patchwork of scars and bionics, the old commissar fights on unbowed.When Ghazghkull's mighty WAAAGH! returned once more to the planet in 998.M41, instigating the Third War for Armageddon, Yarrick came out of a well-earned retirement to lead the planet's defence. None in the Imperium knew the deranged mind of the Ork Warlord better, and the aged commissar was able to counter all but the most outlandish assaults devised by the Greenskin prophet.The cataclysmic and ongoing war that ensued stretched the military capacity of the Adeptus Ministorum to near-breaking point. Suffice it to say that, for all of the ferocity and ingenuity of the Ork Warlord, Armageddon did not fall. The Imperial forces withstood the invaders, though the planet was transformed into a brutal, unending war zone.Eventually, Ghazghkull himself was drawn away by a vision, which he believed was given to him by the greenskin gods themselves. Unwilling to let his nemesis escape only to potentially wreak havoc elsewhere in the galaxy, Yarrick ensured that he was among the Imperial forces who gave chase.Without the tireless efforts of Commissar Yarrick, Ghazghkull's WAAAGH! would have overrun Armageddon long ago and stormed on towards Holy Terra. The commissar's crusade to slay "the Beast of Armageddon" continues to this day.
