1.From Dying World to Living Legend
Fulgrim landed on the resource-starved world of Chemos and turned it from a dying mining planet into a thriving civilization. Even before meeting the Emperor, he was already proving he was destined for greatness.
2.Master of the Emperor's Children
The III Legion was small and struggling when Fulgrim took command. He transformed them into one of the most elite and stylish Legions in the Imperium, famous for discipline, skill, and an obsession with perfection. Unlike many Space Marine Legions, the Emperor's Children celebrated art, music, and culture.Legion Motto: Children of the Emperor! Death to His foes!

3.The Perfectionist
Fulgrim was charismatic, ambitious, and obsessed with excellence. He loved art, culture, and mastery in all things, believing that anything worth doing was worth doing perfectly. This drive made him one of the Imperium's most admired Primarchs—but also sowed the seeds of his downfall. Over time, his pursuit of perfection became an obsession, opening the door to pride, excess, and ultimately corruption.
4.The Fall
Everything changed when Fulgrim discovered a cursed alien blade. What began as a pursuit of perfection slowly became arrogance, obsession, and corruption as the influence of Slaanesh took hold.
5.Horus Heresy
When Horus rebelled, Fulgrim joined him. During the infamous Drop Site Massacre on Isstvan V, he killed Ferrus Manus(Fulgrim's best friend and favourite brother) in single combat, forever sealing his fate as one of the Imperium's greatest traitors.

6.Daemon Prince of Slaanesh
By the end of the Heresy, Fulgrim had abandoned everything he once stood for. Ascending to daemonhood, he became a monstrous servant of Slaanesh, gaining supernatural speed, immense strength, warp powers, and an irresistible aura of corruption. He became the living embodiment of excess itself.

Many considered him one of the most graceful combatants among the Primarchs. Even his rivals respected his skill.
*The Second Primarch #2 was erased by the Emperor, his Legion purged and all records of his existence destroyed, leaving only mystery and speculation behind.
