Silver Reaver

The Silver Reaver was an immense arcane construct, intended for combat against the Iron Horde and built by Derian Silverblade of the Highguard. During the invasion of Tanaan Jungle, the construct was compromised and captured by the Iron Horde, who worked quickly to turn its programming against its 'father' - unleashing the immense colossus onto the Silver Covenant and its conscripted allies.

During a hectic brawl against the machine, Bakuzan, Barsos and Derian himself were captured and locked in the cockpit by its autopilot, and then transported to Hellfire Citadel, where they sat imprisoned for five days. Derian, being Ebon Blade, had no real reason to worry about survival in the construct, but Bakuzan, being organic, barely survived the ordeal - kept alive by Barsos' rudimentary knowledge of Blood, siphoning out impurities and damage to refilter it back through her wounds. This very nearly killed the pair - Bakuzan being without food and the most basic of water, and Barsos expending his runic energy at an unsustainable rate.

The time spent in the Reaver bonded the trio; Barsos developed a begrudging respect for Bakuzan thanks to her stubborn will to live and desire to sacrifice herself for her employees; along with Derian, despite his desire to move past the Ebon Blade hierarchy in favor of returning to his Elven roots; Bakuzan for Barsos, upon hearing comforting stories of his pre-death experiences and struggles to return to a semblance of his former life, and Derian for the pair, having only written them off as inept or incapable of performing in the line of duty.

After a mounted assault on the Citadel by the combined forces of the Highguard, the Alterac Silver Hand (now the Citrine Eagle), the Te'Amun and other allies, Bakuzan, Barsos and Derian were freed. Bakuzan understandably suffered the most from the incident; her lungs irreparably damaged from the toxic fumes of Hellfire; not without its blessings, however, as her constant suffering aided in keeping the two Death Knights somewhat sane during their imprisonment.

The Reaver was sequentially destroyed in what many consider to be Barsos' finest hour - heroically braving the climb up the overridden robot's chassis to stuff its intake ports with, of all things, a pair of Light-blessed panties, causing it to overload and begin a chain reaction that blew its arm off and leading to its implosion.
