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.
