Fulgrim

Fulgrim is primarch of the Emperor’s Children, a craftsman who chased perfection until a Laer blade and his own pride ate him. He wanted his Legion to be beautiful. He made it monstrous instead.

He killed Ferrus at Isstvan V, put Guilliman in stasis at Thessala, and later ascended as a daemon prince of Slaanesh. Chemos, the world he rebuilt, was scoured after he fell.

He still hunts sensation in the Eye. The clone-wars Fabius started in his name are a joke he sometimes finds entertaining. Perfection, for him, is a wound that never closes. The daemon-prince form is a serpent. The vanity is unchanged.

Chemos and Laeran open the fall; Isstvan III and Isstvan V write the betrayal; Terra seats the Siege he joined as a monster; Harmony is the Eye harbour where the Phoenician’s footprint still knots to Abaddon’s Black Legion wars.
