Brother Boreas of the Ultramarines was a Space Marine Scout who was promoted to full Battle Brother by Captain Severus and assigned to the newly-reformed Ultima Squad of the Second Company, where he served as Standard Bearer.[1]
Boreas and his squad were assigned to investigate a distress beacon broadcasting from the Shrine World of Mithron. When he arrived, Boreas discovered that the Imperial Fists guarding the shrine had been slaughtered by the forces of Chaos. Boreas was killed by members of the Black Legion whilst providing covering fire for his Captain.[1]
