(3rd Person POV)
The war had been going on for a while. If you will, the living were facing the dead and weren't doing so well on the grand scale. The Necrons, with their C'tan Masters, were putting in the work and pushing forward on the galactic battleground. The Aeldari, created as a failsafe and hidden ace of sorts by the Old Ones, were taking away some pressure from them and granting them some much-needed respite. But it wasn't enough. The Necrons and the C'tan were pushing on and pressuring the Old Ones more and more backwards.
Among the Aeldari, each battle against the Necrons was a way for them to learn and adapt to each other. The Necrons were using their advanced technology, which was still leagues above anything most Aeldari were capable of. Except for one special group amongst the Aeldari, no one stood a chance in a battle of technology against the Necrons. They used their power over the Immaterium and the experience of the Old Ones to keep up with the Necrons, and while it slowed them down, granted them some victories and maybe even halted the dead's advance, it only did so for a short time before the Necrons pushed further. As the centuries passed, it became apparent that the Aeldari were only slowing down the inevitable. For a proud race like the Aeldari, this was an insult and a hard pill to swallow, so naturally, they didn't give up and used everything they had and more.
Among them, one group stood out. Invoroth Rhyliac and those loyal to his cause and leadership were doing the best amongst the Aeldari race in the war against the Necrons. They were doing so well, in fact, that they were prospering as death and destruction took place around them. This was due to Invoroth Rhyliac's impeccable leadership, immeasurable brilliance, ingenuity and intelligence. His tactical acumen and technological inventions were second to none, and he used each battle to grow more and learn as much as possible while doing precise and calculated blows to the Necron war effort.
His technological advancements allowed the Aeldari to turn the tide once again. In a war where the living faced the dead, the dead would win eventually. It was unstoppable, but the harsh reality. Invoroth, in his brilliance, had changed this and turned the status quo on its head. He had created specialised psychic crystals, an unprecedented mix between psychic power and technology. This marvellous creation acted as a beacon for the souls of the deceased Aeldari. Those who were powerful enough, and that was all of them, could move through the immaterium towards the psychic soul crystals. From there, they were then sorted into cloned bodies of themselves, which had been prepared beforehand.
So the endless respawning of the Necrons was now countered by the endless deployment of previously deceased Aeldari. The playing field had been somewhat equalised as a result. But that was not going to be a deciding factor in this war, not by a long shot.
.
On the ground, hundreds of Wraithlords zoomed across the battlefield. Towering far above their brethren, the Wraithlord was a force to be reckoned with, as it was a warsuit for the Aeldari as Invoroth created it. An Aeldari was encased inside it and connected to his brain, allowing him to control its movements as if he were moving his own body. It was made of modified wraithbone, a psycho-plastic substance, essentially solidified warp energy that an Aeldari manipulated into any required shape. It was stronger than any known plasteel and harder to damage than adamantium.
The Necron Destroyers were shooting at the Wraithlords, who zoomed across the battlefield in complex patterns. Invoroth equipped the Wraithlords with all-around rollerblades, allowing them to shoot across the battlefield and change directions immediately, literally, should it be required. Mobility was a strong suit of the Aeldari, and Invoroth's followers were the fastest faction in the setting. The Ghostglaives and missile launchers picked apart the Necrons one after the other, while the Necrons tried to hit them with their Gauss Cannons, something that was usually very effective against armoured vehicles and soldiers. But to the Necrons' surprise, the gauss cannons hit the Wraithlords without doing anything. Or so it seemed.
Invoroth had extensively researched the Necron technology he could access and had devised a way to temporarily counter the effects of Gauss weapons. Using massive amounts of energy, he could overpower the Gauss Weapons' effects and keep the electromagnetic bonds intact, making the Gauss weapons useless. However, this method required enormous energy, which limited its use for now. Invoroth was already in the process of creating new and more efficient energy cores, knowing full well that deployable, limitless arcs were the goal.
A Deathmark's shot hit a weak point and penetrated the Wraithlord, killing the Aeldari inside it. The Wraithlord, however, didn't fall to the ground. In the off-chance that the Aeldari was killed, the onboard computer and integrated algorithms took over and moved the Wrathlord if possible. Seeing the effective kill as their chance, the Necrons immediately employed this new strategy of sniper shots from the Deathmarks who teleported in range. But they were not the only ones who had adapted their battle strategies. Seeing that the moment had arrived, all of the Wraithlords who had been wreaking havoc on the battlefield suddenly zoomed away in different directions.
Not seeing the logic in this action, the Necrons simply marched forward, as was their programming, constantly firing their weapons and trying to kill anything that moved and lived.
*BOOOM BOOOM BOOOM*
The ground shook as in front of the marching Necron Warriors and Immortals, large Phantom Seers landed. These had but one task: load their enormous Warp cannons and fire them at the Necrons, destroying their formations once a lot of them had gathered in one place, which is what they are doing right now.
*VVRRROOOOOOOOOOOOOMMMM*
Aeldari Flyers shot forward amidst the destruction and targeted specific Necron Arks, destroying the support sent in response to the Phantom Seers. Canoptek Doomstalkers walked forward, attacking the flyers in the sky, and the Aeldari sent out Grav Tanks in return to counter this. Sentry Pylons tried to remove the air support, but were constantly dodged, despite their impeccable targeting systems. No matter what the Necrons tried to calculate, they were countered, and their strategies were prevented immediately, as if the Aeldari knew what was coming.
On the Twilight, the spaceship Invoroth was on right now, a special room, the command centre had been upgraded, and more tools and equipment had been added. But their most effective and newest addition was the head of a Necron. Tubes and various lines ran from the head to the computers, linking the command structure to all the millions of inputs the Aeldari sent back to this place. This particular Necron was the Necron Lord Asmanokh of the Xun'bakakht Dynasty, who was defeated during their first confrontation. Invoroth had made 'good use' of their spoils.
Through Immaterium shenanigans combined with Invoroth's endlessly growing technological prowess, he trapped the Necron Lord's mind. He destroyed his personality completely and only retained his mind after downloading all his knowledge. Now, the former Necron Lord served as a calculator for Invoroth and his forces. A very, very advanced calculator, but a calculator nonetheless. By sending back live inputs, all the Aeldari fed the Necron computer data and information, which it then used to generate counterstrategies and predictions. The Necrons were fighting against themselves at this point, but not only.
Invoroth, in his wisdom, knew that what they were doing was prone to backfire, so he took extensive countermeasures. The Necrons weren't truly fighting as themselves, but followed the wills of their C'tan masters. This meant they were not acting purely on logic at all times yet and were vulnerable to their C'tan masters' emotions. Invoroth had turned each battlefield into a game of 5D-chess, and he was cheating.
"Yratyr," Invoroth said to an Aeldari who had stood at the far side of the room.
As soon as his name was called, he opened his eyes and stood at attention. He wore special armour, designed by Invoroth himself and held a special sword in his hands, sheathed to prevent the damage from spilling into the command room. Something about Yratyr was differnet from the other Aeldari under Invoroth's command.
"You're up."
Yratyr bowed and activated a special mechanism on his suit. He shimmered and then disappeared from the room.
.
The seeming chaos on the battlefield suddenly changed. The psychically sensitive Aeldari immediately sensed the arrival of a new variable. Yratyr had teleported on the battlefield, a short distance away from the advancing Necron front. He stood there with the immaculately crafted blade in his hands, still sheathed but pulsing with red colour. The pulses grew stronger, resonating with the Aeldari spirits and their souls, permeating the entire battlefield. Seeing a new flesh in their path, the Necron Destroyers targeted it without pause.
However, the incoming Gauss attacks were negated by the red pulse of energy coming from Yratyr's blade. Finally, he opened his eyes and, with slow movement, he slowly and deliberately closed his hand around the hilt. The moment his fingers made full contact, the pulse stopped.
For a single heartbeat, the battlefield fell into an unnatural stillness, as if reality itself were holding its breath.
Then he unsheathed the blade... Anaris.
The blade emerged in a violent psychic scream, a wave of raw, violent power and emotion tearing outward as the sword was freed of its restraints. The air warped and bled red-black light, and the Immaterium flinched as if slapped. The colour of the battlefield shifted, from the Gauss greens, greys, and cold metallic silver to crimson and obsidian, as war itself had arrived.
Yratyr's psychic limits shattered. He did not resist it but welcomed it, giving himself fully and voluntarily.
The blade drank, tearing open every restraint Invoroth had so carefully allowed to exist. All the savagery, all the bloodlust, every buried instinct for violence that lay coiled within Yratyr was unleashed at once. His soul burned, as the accumulated fury of an entire species roared through him and flames erupted from within.
Not fire as mortals knew it, but Khaine's fire, black and red, impossibly hot, edged with divine wrath. It burst through his skin and armour alike, immolating him from the inside out. Flesh did not burn away so much as it was transformed. His body grew, expanding violently, his silhouette stretching higher and broader as reality struggled to contain what he was becoming.
Plates of pitted, ancient iron forced their way through his form, replacing flesh and warplate alike. Each slab locked into place with a sound like colliding tectonic plates, forming a towering body forged for nothing but slaughter and war. Where blood had flowed moments before, boiling magma now flowed, cracking through seams and joints, dripping and splashing onto the ground, where it scorched the earth into glass.
His face was no longer mortal.
It hardened into a grim, wrathful mask of iron and fire, eyes blazing like twin stars. From his head a crown rose, a war-crest of burning rage that lashed and writhed with every surge of emotion pouring out of him.
Yratyr was gone. In his place stood Khaine, not an echo, not an avatar awakened, but the newly born god of battle, war, violence, murder and conflict given a vessel in realspace.
This was Invoroth's newest creation, and to date, it was his most impressive creation. Naturally, he knew what he was doing and realised that this was only going to cause chaos down the line, but the damage had already been done. What happened, what was happening, and what would happen were not linear in the Immaterium. Some things couldn't be prevented. The war between the Necrontyr and the Old Ones had done a lot of damage already, and the second iteration of the War in Heaven, this one right now, had already done too much damage to stop the emergence of the three Chaos brothers.
Invoroth had taken the unpredictable and made it predictable, on his terms. The Aeldari were a species with set limits and finished evolution. What Invoroth had created was a blade that broke the psychic limits of the Aeldari who held the blade and unleashed their rage and savagery. In doing so, the warrior using the blade rose in power so immensely that he theoretically became an unstoppable machine of destruction.
This, however, had consequences. The collective emotions of the Aeldari of battle, war, murder, violence and conflict, accumulated as one, and elevated the construct of Khaine into a literal Warp god, but not in the same sense as the Chaos ones that would appear.
Yratyr had agreed to become the bearer of Anaris, sacrificing himself to Khaine. Because by wielding Anaris, Khaine took over and manifested in realspace, literally fighting alongside the Aeldari against the Necrons. Invoroth had indirectly created the Aeldari Pantheon and made them fight alongside him and his forces.
