From Warhammer 40k - Lexicanum
→Horus Heresy
Fulgrim and the Emperor's Children were the first to arrive in the [[Istvaan system]], Horus' forward base, and Fulgrim met Horus in person, demanding a personal account of his actions. Instead, Horus was able to sway Fulgrim to his cause. Fulgrim's respect for Horus allowed Chaos to find its way into Fulgrim's heart, destroying Fulgrim's loyalty to Terra, and replacing it with burning desire to destroy the man who held humanity back from the perfection Fulgrim desired. [[Slaanesh]] whispered to Fulgrim, and Fulgrim accepted the promises of his new god.
The rot spread from Fulgrim to his lieutenants, the [[Lord Commander]]s of the [[Legion]], then to company and squad leaders, and finally all but a bare handful of Marines followed Slaanesh the Emperor rather than the EmperorSlaanesh. Perfection became perfect hedonism. When the loyalist legions arrived in the Istvaan system, the Emperor's Children were at the forefront of the fighting, aiding in the massacre of their former brethren.
Horus' rebellion spread, bringing the entire Imperium into civil war. All trace of decency amongst the Emperor's Children had vanished by the time they partook in the Siege of Terra. While other [[Traitor Legions]] assaulted the [[Imperial Palace]], the Emperor's Children embarked upon a spree of terror and gratification amongst the helpless citizenry of Earth. Billions of defenceless civilians were used as experimental subjects in the effort to create ever-more powerful stimulants and pleasure-inducing chemicals, used to suffer daemons, or were simply killed to sate the bloodlust of the Legion.
