Alpha Primus

Alpha Primus was the name of the being who served as the prototype for all other Primaris Space Marines. He now serves as the personal assistant and agent of Archmagos Dominus Belisarius Cawl, the creator of the Primaris Astartes. Alpha Primus was originally created by Belisarius Cawl in an attempt to recreate the process the Emperor of Mankind had used to engineer the primarchs before the Great Crusade, in order to extrapolate backwards from that process a more superior breed of Space Marine. The process failed, however, due to Cawl’s lack of knowledge, and instead Alpha Primus was used as the prototype for what later became the template used to engineer the Primaris Space Marines on the order of Roboute Guilliman before his mortal wounding at the Battle of Thessala in 121.M31.
