Garro was proud to bear the title and approved of upholding the traditions of the legion, including the use of a housecarl, Kaleb Arin, to act as his equerry. By the time of the Horus Heresy, Garro was one of the few originally Terran Marines still serving in the Legion, which caused a rift between him and his fellow Captains, who often called him 'Straight-Arrow Garro.' Battle-CaptainĪs Captain of the 7th Great Company, Garro was entitled to the honorific title ' Battle-Captain', a tradition of the Legion dating back to the Unification Wars on Terra, when an officer of the XIV Legion distinguished himself in front of the Emperor, who bestowed the title on him as reward.
Born on Terra, in the region of that world known as Albia, Garro enlisted in the Dusk Raiders Legion, as the Death Guard was known before its reunion with its Primarch, Mortarion, and its relocation to its new base on Barbarus.
