horus was obliterated by the emperor himself, although he was mortally wounded. sanguinis, primarch of the blood angels, was killed by horus, but managed to inflict a chink in horus’ armor in order for emperor to destroy horus with his psychic powers thru’ that lobang. rogal dorn, primarch of the imperial fists, survived the assault on the flagship and carried the wounded emperor back to the throne room. there, the emperor survives in a contraption called the golden throne with his soul while his body decays and rots away. thus, the emperor didn’t really lose the battle with horus.
his origin. because shamans couldn’t reincarnate individually after their deaths, they would eventually go extinct as each were to die out. they decided to have a shaman world conference and sacrifice themselves in a mass suicide to create a reincarnation of millions of shamans into one man. he’s reborn in anatolia, part of turkey, to a sheep herder and his wife. born as a farmer/herder, he leads a very humble and poor life when young but imbued with godly powers. very similar to the jesus story.
