It was only inevitable that he would left alone with his thoughts for company.
He knew that, by not heeding his first boyfriend's warning, he died at the hands of his bride Charlotte. He didn't know what happened to his body after death, but there was some suspicions that his physical form would have been taken by Charlotte so that she'd possess him forever like one of those overly-obsessive yandere types. While he held onto hope that his body was taken in by police and given a decent burial in a grave that Charlotte couldn't track down, that hope was fleeting.
"At least they don't have to worry about salting and burning my bones like in Supernatural," he thought to himself. "I'm very sure that this place trumps over normal religious lore."
He was right. He couldn't feel connected to his original world nor to his own remains like a vengeful spirit or demon from Hell, yet he had expected something. He had expected to possibly haunt his own body or be connected to some item with some sort of lingering attachment to it so he could witness what happened, but this strange place beyond what he understood as time seemed to possess strange laws that sever connections to the original world.
"But I still have questions," he thought to himself as he returned to dwelling on his emotions. "Why is it that she killed me after marrying me? What kind of sick fantasy would make her kill her newly-wed husband on their wedding day in achurch?"
He was trying to ask questions that he couldn't possibly answer by himself. These types of questions often drive the asker insane as if trying to dictate other people's logic to a wholly incompatible line of thinking. This was, in part, why he was so angry with his own death and the circumstances surrounding it.
It is also this type of anger, the one felt by those who have died from a grievous injustice, that is a near-perfect fuel for Umbramancers and Necromancers alike.
To put it in perspective, Sith from the Star Wars universe barely scratch the surface of harnessing their emotions. They rely on superficial anger and rage that only comes about in specific scenarios to power their Force abilities (like Force Lightning), but could not imagine what it costs to power abilities that even false Sith during the Galactic Empire era would shy away from. That superficial emotion is far inferior in respect to what he feels now.
As for why this type of emotion is a near-perfect fuel?
Well, that is because the feeling of maddening injustice for the crime and outrage from the victim of said crime is potent enough to either cause major damage by itself or form a perfect core for advanced magic. Umbramancers (or Shadow Mages) can utilize this kind of power far more efficiently than even pureblooded Sith Lords to bend the rules of reality itself for their own purposes. The inner turmoil caused by such trauma can produce powerful variations of common Shadow spells to the point their illusions can be on par with an Adept-tier mage at the very beginning.
However, that is just for Umbramancers. When that kind of power is in the hands of Necromancers (or Death Mages), it is a far different story.
Beings who have experienced Death, embraced it, or simply felt its presence on the other side of the Veil that hold onto this level of anger and madness could enhance their very essence and condense what most practitioners of the necromantic arts would call a "core of vengeful heart" which grants them the power to command entire worlds of dead with very little effort. To those who have died before their time, the actions of a necromancer with a vengeful heart core to raise them both eases their transition into the next life and poisons their essence from the caster's own anger.
In a very oversimplified way of speaking, the caster's own emotions act as an anchor of its own accord and prevents the caster from being reaped by Death itself in exchange for immense power and agony.
As for him who stews within his own turbulent emotions within the Abyssal Sea, the effect of making such a powerful core is vastly increased in both potency and difficulty. While the normal route of him getting justice by his boyfriends against his murderer should have corrected these emotions of his enough to give himself peace, it is the unknown aftermath that ensured his emotions remained heightened within this place. This essentially turned his potent rage inward and created a Crucible effect.
Thus, he had unknowingly attained a place and means to condense a higher-tier core that had the potential to harness greater power.
"I hate what happened," he thought to himself as he unknowingly began to dwell deeper into his circumstances. "I just wanted to make my parents happy, soothe their desires, and potentially keep what fragile hope I had for the future. I wanted the comfort of my boys and the warmth of a home with them, away from the stress of so-called normalcy. I was selfish for wanting something while wearing a mask. I hate that I didn't heed Jason's warning. I hate that bitch Charlotte for what she did to me. I just wish I could..."
Then, like a bubble floating to the top, a memory surfaced.
He remembered Jason and his other two boyfriends a month ago playing an old tabletop game. He wasn't too involved then in the game itself, but the lore was enough to get him hooked int buying books and a one-time deal of subscribing to a exclusive platform full of animations and shows of this specific franchise. Jason didn't have much experience with this universe outside of knowing bits and pieces of the lore too from his original world, but the other two boys in their strange four-person relationship knew very intimately about this universe.
One played for the Mechanicus team in most tabletop games with very rarely playing as a Adeptus Custodes. The other played for both Chaos and the Imperium.
Arnold was the Tech-Priest sort and even graduated from MIT. A natural-born genius from what Jason told us through the System.
Steven was the type of guy who loved to play both the heroes and villains. He didn't mind playing either for the Imperium as a Rogue Trader or as a chaos-spawn heretic. What was amusing to him was that Steven mostly favored Khorne's forces than either Tzeentch or Slaanesh.
The arguments he heard from Arnold and Steven about Warhammer 40k brought him both a small measure of soothing peace and searing agony from the memory. He'd never see them again, but there was something he felt he could do to aid himself in this place.
"In the grimdark future of Warhammer 40,000, there is only war," he began thinking as he decided to take control of his emotions. "While the Imperium itself fights against the forces of Chaos daily, human blood is spilled across the vast territories it occupies."
Within his thoughts, he focused on a single mental image. His agony and rage began to condense within his spectral form as he focused deeper on that specific image.
A corpse, bloodied and wounded, sitting upon a Throne that looked golden. This corpse still possessed endless and boundless vitality within its very existence, but His psychic might triumphed over all within the vast Imperium. He didn't know if this ancient human-centric existence could hear his meager prayer from within the Abyssal Sea as it isn't a place of the Warp, but he didn't care. All he needed was His image to center on.
To the forces of Chaos, they call Him the Corpse-Emperor.
To the forces of the vast Imperium, they call Him the God-Emperor.
"An image of ancient suffering, yet still living," he thought to himself as he continued to harness and compress his anger and insanity within himself. "Forever bound yet ever vigilant. The only person to fight and win against Chaos itself. The Master of Mankind."
When he finished that thought, something happened that granted him a deeply profound sense of relief. Within his very spectral form, unseen by his own eyes, lay a pitch black core. His negative emotions became less enhanced and influential on his judgement, but that wasn't all.
He felt like traces of this place were imbued into his very essence. He was, somehow, linked to a very tiny part of the Abyssal Sea but that part was enough to stabilize everything in a state of perpetual permanence.
Then, an impossible thing happened.
