(General POV)
Location the Blood Lands near the Skull Throne
The two Chaos God of the Immaterium both been greatly injured by other once again staring the other down catching their breaths from all the damage they were inflicted, as Laharl decided to make the first move this time by casting several Dark Bolts at his brother the first hitting the right side of his brass chestplate causing the Blood God great pain and darkness damage as the other Dark Bolts he managed to willstand and barely avoid as Laharl closed the distance and tackled Khorne to the ground using his frontal leg-claws to pin Khorne down as he pummeled him with punch after heavy punch which every blow caused the ground to shake as Laharl beat his younger brother.
Khorne doing his best wullstanding the punches of his brother started bending his power through his body causing it to once again ignite completely in hellfire, the blazing heat of his hellish flames forced Laharl to release him taking advantage of the opportunity he toss a huge fireball at Laharl's face exploding on impact, burning the Dark One as Laharl was tending the burns the best he could Khorne struck smashing his fists on Laharl's back then stomped on his center point and unleashing a stream of hellfire upon him with no tail and unable to shield himself the Dark One felt the full brunt of Khorne's hellfire until Laharl wullstanding the fires channeled his Darkness divinity through his entire body taking inspiration from his little brother along with using his Physical Shift ability to transform into his Shadow form phasing through the earth escaping Khorne's attack as Khorne realized Laharl has escaped him he cut off his hellfire stream, and started looking for him not noticing the rising shadow behind him using Physical Shift again to return to his True Chaos God form he grabbed Khorne by his waist lifting him above his head and slamming the Blood God hard against the red earth of Blood Lands.
As the two continue fighting ferociously so do they're respected daemonic legion some distance away from them.
Location the Blood Lands the battlefield, Khorne Daemons Vs. Laharl Daemons
Skarbrand was leading the legion of khornate daemons currently he just kick a Knightmare across the battlefield, and cleaved straight through several Slaughter Calvary as Knightmare rider and Darkstalker mount was killed/banished back to the Nethervoid to reform as he was pelted with Warp rays from Observers were floating around bombarding the battlefield enraged Skarbrand roared turning his blazing gaze towards a couple of Blood Thrones he roared at the to focus their fire on the Observers obeying him the Bloodletters operation the daemonic cannons readjusted, took aim and fired at the aerial one-eyed beasts of Carnage taking down some of them as they squeal in pain and fall to the ground covered in flames as they kept attacking them until the Dark Druid Queen, Chi Aahtahg commanded them to reposition away from the main battle.
Skarbrand seeing this praised Khorne and ordered some fellow Bloodthirsters to follow him into battle as they charge into a another force of Knightmares.
The battle was literal blood and carnage directly affecting both daemonic legions empowering them and making them more excited for more bloodshed/carnage but at the same time they were indirectly aiding their respected God in their own battle between themselves.
As Skarbrand engaged the Daemon Queens, Chi Aahtahg and Kiira Blakenroze with his axes clashing against the queens own chopper and ring blade the Bloodthirster swung his axes (Carnage & Slaughter) down on the wives of the Dark One this death-lock was fierce as Skarbrand could not believe the strength these women possess not only forcing back his blades but looking at them he could see they were holding back as this infuriated the Greatest of the Bloodthirsters he roared releasing a blazing hot breath down on the Daemon Queens as he yelled "You dare!!!! You dare to look down on me!!!?" earning him a confused look from Chi and Kiira as Skarbrand voice lowered but it was still filled with unrelenting fury "You two...the mates of a Dark God. Possess untold power I've witnessed it around this battle. And yet...YOU DARE NOT FACE ME SERIOUSLY I'LL HAVE YOUR SKULLS, AS MY CHALICES TO DRINK YOUR DIVININE BLOOD!!!!!" releasing large amount of killing intent and rage upon the two Daemon Queens but they were not effected in the slightest.
Both Chi and Kiira responded to Skarbrand's threats and injured pride as a joke even chuckling turned into laughter as they said "It because our beloved told us to humiliate you, not challenge you." Kiira glazing at her left towards Chi sending a signal which the light grey skinned Dark Druid Queen responded with a fanged grin releasing one of her claws from the handle of her chopper to manifest her daemonic wooden staff she channeled her dark druidic power through the staff making the top glow in violet warp-energies once she has charged enough Chi fired a huge energy projectile directly to Skarbrand's chest causing to gasp and spit out some blood and sparks of fire as he was blasted away smashing through both Blood and Carnage daemons as he finally hit red ground digging into it some from the force of Chi's attack.
Grouning as Skarbrand forced his cloven foot onto the crimson earth and slowly stand as the magical attack of the Dark Druid Queen was something that the Bloodthirster was not expecting, shaking his head to clear the pain and slight disorientation, he blinked his crimson eyes a few time as he managed to see a figure soaring at unbelievable speed towards him once his vision cleared he saw Kiira the Succubus Queen with her wings spread flying directly to him without her weapon but her body was glowing in a pink-magenta color seemly surging through her body onto her gloved hands which were glowing the brightest and intensifying both in tone and power as she was flying towards him, despite the pain Skarbrand refused to lose to some women that dare spit on what a true battle is metal against metal, blood spilling everywhere roaring he picked up his axes and rushed directly at Kiira meeting her attack head on.
Stomping his way to Kiira Skarbrand spread his wings and flew at great speed towards the succubus matriarch eager to claim her skull and bath on her blood, just when the two powerful daemons were about to meet Skarbrand with his axes rised eager to taste blood while Kiira has finished gathering her lust energy into her hands as her arms were slightly spread and bended ready to strike.
With great brutal force Skarbrand struck but aside for all that might, power, and size he was much slower then Kiira who avoided his swing using her speed to rush faster into the Bloodthirster unable to defend himself he was struck with the full brunt of Kiira's attack smashing her hands into his belly as the ruinous power of Lust surged through her hands onto Skarbrand poisoning, corrupting and hurting him both physically and mentally as Kiira smiled sadistically watching the mighty Skarbrand roar in pain she did just like her sister and blasted away the Greater Daemon of Khorne, away by pure force of will and strength he managed to hold on to his axes as he soar through the crimson skies of the Blood Lands eventually crashing into the ground forming a deep crater and also killing/banishing several daemons from both sides with his impact against the ground.
As Chi and Kiira reunited they commanded their forced to advance and join their Dark God in his moment of triumph over Khorne all gathered and killed the khornate daemons that refused to submit as they organized behind Ladies Chi and Kiira, along with the Elder Daemons Ba'al and Mordred marching toward the east, towards the Skull Throne serving as the final battle between the two Chaos Gods.
From the side of Khorne the daemons raged from the disrespect they suffered under the Carnage Daemons as they abandoned the battle and treated them like a worthless nates before they could chase, from Skarbrand's crater a huge burst of flames erupted along with the sound of a raging beast which stopped the legion of blood in their tracks as they turned towards the origin of the flame, hatred, and bloodlust they all feel.
Crawling out the crater was the Rage Incarnate, Skarbrand covered in burns and bleeding wounds especially his head as it poured boiling blood onto the ground, panting and crotched over, tightening his grip on Carnage & Slaughter, spreading his red wing he roared with such intensity that all khornate daemons back slightly away from the Bloodthirster fearing to be the source of Skarbrand's fury "calming" down he turned his head around searching for the Daemon Queens that dare humiliate him he looked down at a lone bloodletter tossing one of his axes into the ground he reached out and grabbed the lesser daemon around his red neck, choking him Skarbrand brought him close to his face and roared out "WHERE ARE THEY!!!?" the bloodletter in a choking voice responded the Bloodthirster the answer not amusing him so he crushed the lesser daemon's neck tossing the corpse aside picking up his discarded weapon, and stomping slowly forward he rise his right arm and screamed "BLOOD FOR THE BLOOD GOD!!!!! SKULLS FOR THE SKULL THRONE!!!!! MAINE!!!! KILL!!!!! BURN THEM ALL!!!!!!" hearing his word reignited the battle and bloodlust within all his fellow daemons of Blood as they chased after the Carnage Legion.

Khorne was smashing against the brass steps that lead up to his throne as his brother just threw him there rolling aside in time to avoid Laharl's Claw of Hades from impaling him Khorne responded with a left cross to his brother's face forcing the Carnage God to back away as Khorne slowly was standing using his stairs for support as they been beating one another for days, months, years time means nothing in the Immaterium but one thing was certain they both look a whole lot more worse then when they started as lava pour out the cracks, slashes, and deep dents of Khorne's armor while the Blood God managed to tear off his brother right wing and clawed his left eye which those wounds were pouring darkness blood the two Chaos Gods we're reaching their limits as they both sense their respected legions fast approaching they both decided to end this exciting fight with one final struggle.
