Roboute Guilliman, Primarch of the Ultramarines

Roboute Guilliman, the Primarch of the Ultramarines, is a key figure in Warhammer 40,000. Known for his strategic genius and administrative skills, he authored the Codex Astartes and rebuilt the realm of Ultramar into a prosperous beacon within the Imperium. Critically wounded and placed in stasis for ten thousand years, he was resurrected in the 41st Millennium. Upon his return, Guilliman found the Imperium besieged by enemies and decay. Assuming the role of Lord Commander, he launched the Indomitus Crusade to reclaim and stabilize the Imperium, symbolizing hope and renewal amidst the grim darkness of the far future.
