Khorne

Based on https://warhammer40k.fandom.com/wiki/Khorne

Although extremely based on this deity from 40k Khorne in this setting should be described by this edited passage from his wiki page "Khorne, also called the Blood God and the Lord of Skulls, is the Chaos God of Blood, War and Murder. His domain covers the most basic and brutal of sentient emotions and actions, such as hate, anger, rage, war and killing. Every act of killing or murder in the material universe gives Khorne power; the more senseless and destructive, the better. However, though Khorne is the god of bloody slaughter, he is also the god of martial pride and honour, of those who set themselves against the most dangerous foes and earn victory against the odds. A devotee of Khorne is as likely to be an honourable champion in combat as a blood-crazed slaughterer. Khornates take no artful approach to killing, seeking only to slay rather than to inflict pain, because while the blood of their victims strengthens Khorne, their suffering actually empowers his nemesis Slaanesh. The name "Khorne" derives from his name in Abyssal, Kharneth, meaning "Lord of Rage" or "Lord of Blood". He is the mightiest and the oldest of the major Chaos Gods.

Khorne is the Blood God, Lord of Rage, Taker of Skulls. He is wrath incarnate, the embodiment of a never-ending lust to dominate and destroy. It is his sole desire to drown all the existance in a tide of slaughter, to conquer and kill every living thing until there is nothing left but spilt blood and shattered bone."

In this setting Khorne was the first born of one of the Primordials being the second one Slaanesh, with this being said Khorne was meant to be amongst the many layers of the Abyss but when he was born there was no Abyss only a space where the Abyss would be which led to Khorne eventually like the Primordials themselves to be locked outside of time and space in the eternal void. None the less there is a big diference between Khorne and his fathers because since he was not amongst the Primordials he cannot be considered one of them thus having avoided their fate of being unable to reach any of the other planes and touch was all he needed. For when Khorne touched the lands. Touch was all that was needed for his touched made a prophecy "fFor three hundred years the war will wage, then the first of many shall awake, for fifty years silently word will spread and on the dawn of the first day of the fiftieth year the Khornate will rise as the Sons Of Blood, Skulls and War" and so it did. Now on the fields of the Flaeness his chant can be heard "BLOOD FOR THE BLOOD GOD, SKULLS FOR THE SKULL THRONE"
