The 3rd Founding of the Space Marines occurred during the first year of the 32nd Millennium, 001.M32. This Founding included two Successor Chapters created from the gene-seed of the Imperial Fists and the Ultramarines, respectively -- both highly aggressive Chapters.

The Executioners are scions of the proud line of the Imperial Fists. Founded under the command of Fafnir Rann, reputedly the most vicious of Primarch Rogal Dorn's later Captains, they were created for the sole task of seeking out and slaughtering Mankind's foes rather than undertaking a more defensive or strategic purpose.

The Scythes of the Emperor are a fierce and proud Chapter created from the lineage of Roboute Guilliman. Their origins can be traced back to the bygone era of the Horus Heresy, when they were originally members of the Ultramarines Legion's 199th "Aegida" Company, who were assigned as sentinels over the restricted world of Sotha, and the mysterious xenos artefact known as the Pharos.

Following the Second Founding in 021.M31, Guilliman charged the remaining members of Aegida Company with continued watch over the secrets of the Pharos as an 11th "ghost company" of the Ultramarines Chapter, in direct contradiction of the dictates of the Codex Astartes. Later, during the 3rd Founding in 001.M32, Captain Oberdeii, the last surviving member of Aegida Company, was reassigned as the first Chapter Master of a newly created Chapter which he renamed the "Scythes of the Emperor."

They continued their vigil over Sotha and the surrounding sectors in the Ultima Segmentum. Recently, they faced near-annihilation at the hands of the Tyranids of Hive Fleet Kraken in 992.M41. Though severely depleted, the surviving Battle-Brothers of the Scythes have vowed to wipe out the remnants of the Tyranids in the Ultima Segmentum, even while they continue with their efforts to rebuild the Chapter. The recent reinforcement of the Chapter by the Primaris Space Marines of Roboute Guilliman's Indomitus Crusade have allowed them to go on the offensive against the enemies of the Emperor once more.
