Edoraki Hakon was Marshal of the Imperial Army during the Great Crusade and Horus Heresy. Stationed under Lord General Tyana Kourion's Molech garrison, Marshal Hakon oversaw the world's Northern Oceanic Theatre. During the Traitor Invasion of Molech Grael Noctua of the Sons of Horus attacked Hakon's command bunker, slaughtering all inside. Hakon was badly injured and found on the floor, Volkite Pistol in hand. Noctua told him that he should aim well, and Hakon fired directly through one of Noctua's hearts. He was then gunned down by the traitor's Bolter.
