(General POV)
Location the Blood Lands, near the Skull Throne
Both brothers gravely wounded despite being god entities of the Immaterium they were both bleeding their respected form of blood, raging liquid flames of lava for the brass armored Blood God and literal liquid darkness for the Dark One.
Neither of the Chaos Gods has back down or submitted to the other as their war, soon turned into a duel which ended in a vicious brawl that cross all throughout most part of the daemonic domain of the recently born Khorne, as Khorne possessed the higher ground standing upon his brass stairs leading up to his infamous throne, as he looked down upon his opponent and brother Laharl, Chaos God of Carnage both has beaten, burned, blasted, clawed, slashed, torn, and much more on the other to win their bloody battle as each of them were panting, feeling untold amount of pain and signs of fatigue they also felt excitement as their fight was close to its conclusion.
As both Gods felt their respected daemonic legion fast approaching their fighting ground as both armies were barely noticeable as they came from the crimson horizon of the Blood Lands with the Daemon Queens leading the Carnage Legion and Skarbrand the Blood Legion.
They were about to clash against one another when the daemons saw the state of their respected God filling them with rage and turning their attention onto the opposing Dark God to attack when both Laharl and Khorne spoke/commanded their daemonic followers not to interfere or continue to fight only to witness their battle that will decide the victor of this battle.
Obeying their Gods both armies began to head into opposing sides surrounding the Blood God and Dark One making a makeshift ring for them to do battle as Khorne walked down the steps onto the crimson ground watching as his older brother back away a bit leaving some space to plan their next attack on the others, as the two began to circle one another never breaking eye-contact waiting for right moment to strike.
As the Neverborn of the Warp watch with anticipation for the upcoming bloodshed praising their respected Chaos God when both of them stopped circling standing before their daemons in the next moment the two brothers charged forward with there's respected right arm drawn back as Khorne and Laharl swung with all their might.
The Chaos Gods fist was caught by the other as the two grappled against the other's strength smashing their head/helmet against the other trying to push back the other and break the death-lock between them.
While Laharl would have used his tail Khorne burned a chunk off, both of them couldn't use their wings for different reasons, and a headbutt would be also out of the options for the other would immediately counter with a headbutt, so they use their respected ruinous power to break their death-lock Khorne charging a eye beam while Laharl was charging a Warp-ray through his mouth as both fired their attack at point-blank distance, the blast knocked the other away greatly damaging themselves from the combine power of their respected beam/ray as all the daemons cheered, praise, and roared in admiration towards their God as both of them were starting to stand again and it was Khorne who struck first this time.
Khorne's rage fueled him as he was the first to stand and strike after their energy attacks collided with one another, seeing his daemonic/draconian brother getting up slowly he took advantage going next to Laharl and punching him in his blind spot stun by the blow to his injured eye, Khorne placed Laharl in a choke hold trying to get the right grip to snap his neck but Laharl managed to struggle enough to place his right claw between his armored arms preventing Khorne from securing the grip as they struggle Laharl managed to rise his left clawed gauntlet hand and bring it down with force onto Khorne's left thigh stabbing through his brass armor as the massive, razor-sharp, armored claw dug into the Blood God's thigh and Laharl used brute force and movement to enhance the pain which Khorne responded screaming in pain lessening his grip around his neck allowing for Laharl to reach around the side of Khorne's head with his right claw and using all his strength with the added aid from gravity dropped, smashing the Blood God's head over his right shoulder causing great damage to his shoulder and his brother's head letting him go.
With his claw free covered in infernal lava which is Khorne's blood plus stunned from the head drop Laharl just gave Khorne he charged swinging his Claw of Hades at his younger brother who reacted to late as a titanic clawed gauntlet just swung across his head hitting/clawing into the right side of Khorne helmed face the blow backed up by Laharl's strength and the blazing liquid flames of Khorne's blood which actually tore a chunk of not just Khorne's helmet but his face too as lava soared across the battleground and Khorne had to make distance between them as Khorne turned to look at Laharl exposing his true daemonic face which Laharl had to admit it greatly resemble Diablo from Diablo III version as his swipe tore off his right cheek exposing the white lava covered razor blades that are Khorne's teeth his dark red skinned daemon face focused on him as he started to laugh causing more of his infernal blood to spill onto the Blood Lands as he spoke "Regardless of what happen next! Or Millenias from now brother!!! You have proven to be a true warrior!!! I swear to honor you skull and that of your mates above my throne to never forget...!!!! who has provided me with such a fight!!!" Laharl knew this was Khorne's form of praise and admiration to a enemy and thought that has gained some respect from his younger sibling which made him laugh spreading his arms as a motion to Khorne to bring it and the Lord of Skulls did not disappoint stomping his way towards Laharl.
All we're amazed with the clash of the two dark ruinous powers not more then Skarbrand and his kin not only impressed with the Carnage God's strength, ferocity and brutality but to be able to get such level of praise from their Dark Patron as they heard their master's words and joy filled laugh soon joined by the Dark One as they continue their battle the Bloodletters, Juggernauts, Flesh Hounds, and Bloodthirsters roared swinging their hellish weapons, breathing unholy hellfire into the air praising and chanting the Blood God's name over and over as they began once again to ignore defense and tactic for more brutal bashing of fists this exciting the Legion of Blood as lava and darkness flew and stained the red earth of the Blood Lands this has become a battle of endurance and stamina which ever reaches their limits first shall fall this day.
On the other side of the battleground Chi and Kiira were holding each other tightly with swirling emotions pride, worry, excitement, anguish, admiration and pain as this been the first time either have seen their dear, beloved husband is such a state covered in serious wounds, missing one of his eyes and wing along with a cut tail not to mention all the burns that cover their love's body with time and mortal souls he'll heal but in this battle he might die but they also felt trust on the dark being that has swore to always be with them as they along with their future sisters shall corrupt and rule the Materium together as they kept on watching the battle wishing their beloved fortune all around them the Knightmares, Void Wraiths, Darkstalkers, Apexstalkers, Observers, Succubi, Chaos Corrupted, Dark Florrah we're cheering, praising, and chanting the Dark One's name as he has greatly harm the Blood God more then once in this battle and soon shall come out triumphant!
Back in the fight that has once again devolved into a vicious brawl only this time there was no more evading, no more outsmarting the other, and no more lucky breaks just pure brawl of strength, durability, and endurance.
With that said Khorne was just punched in the stomach only to power through the pain and punch back Laharl across the face this continued for what no being knows as time was meaningless in the Warp they could be fighting for years, at the same time minutes but it was clear that both he and Khorne were at their last legs all that was needed was one blow that will put down the other for good.
This fight carried on and on as they beat each other with no remorse or mercy until...
Khorne ramming Laharl getting into his blind spot and start dropping bombs of punches without relenting hitting Laharl in the stomach, ribs, chest, and face this rush continued as Laharl spat more black blood of darkness from every heavy blow Khorne connected on his body this served to excite the khornate daemons believing it was Khorne's moment to win and slay the Carnage God but the battle and bloodlust didn't serve to benefit the Blood God on this battle as Khorne was so focused on striking he forgot about Laharl's frontal leg-claws which that struck him unsuspectingly in the the left thigh wound as Laharl powered through the pain and burns of his latest punch while Khorne was slightly kneeling Laharl hammer strike his back with both his arm forcing the Blood God to his knees and in height of an uppercut from his frontal right leg-claw.
The force of the blow forced his head back for Laharl to start swinging right, after left, after right punches across Khorne's exposed defenseless face as it was Laharl turn to whale on Khorne he could see the Blood God was losing consciousness so deciding to end their fight and winning this war Laharl grabbed Khorne by the neck with his left gauntlet equipped claw lifting the semi-conscious body of the Blood God into the air silencing the khornate daemons as they watched as Laharl literal back break Khorne using his shoulders causing Khorne to scream in absolute agony then be thrown hard against the ground unable to move.
Stunned into silence as Laharl walked over to the unmoving broken body of the Lord of Skulls, slightly pushing his body onto his back as Khorne looked at his brother as Laharl spread his remaining wings, and arms wide with his head looking to the sky he let such a massive and powerful roar that the entirety of the Immaterium shuke to the Dark One's power, and might as the first chapter of the Great Game of Chaos is closed, concluded in the victory of Carnage and Laharl.
