There was a world whose essence resembled that of a shark's womb, as it was full of newly born life forms that devoured each other. The horror inside this world could drive anyone mad, but that was not something the life forms in it had to worry about, as they lacked true sentience.
Unfortunately, not all the life forms born in this world were lucky. Some of them were born with sentience, and they had to face a horror that was too strong for their weak souls. The chances of one of those anomalies living over a week were virtually zero.
One day a new anomaly appeared in this world. He resembled a larva with a black shell and long spider legs coming out of his body.
The mind and soul of the black larva were a blank slate. There was no evil or good in him, as he was foreign to concepts like those. At this moment in time, there was an infinite potential for goodness in him. He could become a hero that could lead an entire universe to an era of prosperity and absolute glory.
Sadly, he was born in a world where kindness did not exist, and compassion meant death.
Less than a minute after his birth, another life form attacked the black larva. He dodged a deadly blow, but a deep cut appeared on his chest.
The first thing the black larva received was pain, and the first emotion he generated was rage. Without hesitation, he turned to the attacker and dashed full of killing intent.
He killed the enemy and consumed this one's flesh, becoming stronger. A sharp light appeared in the black larva's eyes as he stared at the half-eaten carcass in front of him and then glanced at the surroundings.
The black larva was not the first to be born with sentience in this world, but unlike all his predecessors, he had another gift. He had wisdom like no other and could adapt to the horrors that permeated the whole world.
He could kill enemies much stronger than him, using his wisdom to carry on traps and ambush. Devouring those corpses filled the black larva with energy and vitality, allowing it to rise in the Ranks.
One day the black larva saw how one of the strongest life forms achieved a qualitative evolution, generating a black altar with his soul before leaving the world.
All the other life forms in the world saw that with a fervent sense of longing. They wanted to achieve that no matter what, but the black larva was different.
He saw how that black altar gave immense power and the key to leaving this world, but his instincts told him that the price was something he could never accept.
Every time a life form reached the limits of the world and generated that altar, the feeling in the black larva that something was very wrong grew stronger.
After a few decades, despite his best efforts, the black larva had grown so strong that he would soon undergo the process of creating an altar with his soul.
Anyone else in his situation could have done nothing but surrender to fate, but he was not like everybody else.
The black larva figured out a way to use magic and elemental forces despite having no one to rely on and learning from zero. Using that knowledge, he divided his body and soul in two, generating an avatar.
Breeding that avatar weakened the black larva, allowing him more time to figure out how to handle the soul altar.
Every time he reached the world's limits, the black larva generated an avatar carrying half his vitality and soul force.
Thousands of years passed like that, and the black larva lived each one of them in complete solitude. Almost all the life forms in the world were mindless beasts, and since he did not trust anyone but him, there was no point in searching for others born with sentience.
That loneliness could break even the strongest wills, but the black larva persevered despite everything.
Finally, one day, after generating over one hundred thousand avatars, the black larva decided to take a bet. He sacrificed more than half of his avatars to develop a perfect copy of himself that he could control from inside the world.
He called the copy the Yellow Avatar due to the aura that permeated this one.
After finishing with the Yellow Avatar, he made this one undergo evolution. The black larva felt everything the avatar did and saw how he needed to choose one of the universe's fundamental forces to create the altar.
There were many forces at his disposal, but the one the black larva chose for the Yellow Avatar's soul altar allowed the control over a net that extended through the entire universe.
During the formation of the altar, the black larva felt a horrible agony as something wanted to extend from the Yellow Avatar toward his soul, but he had prepared. He used the rest of his avatars as sacrifices to disguise his soul.
It was hard, but the black larva managed to protect his soul, and the Yellow Avatar evolved and began his exploration of the universe.
Words could not describe the thrill and excitement in the black larva as he could finally explore the universe and see what was out there.
It did not take him long to learn that the name of his universe was the Eldritch Universe and that the black altar that life forms generate as they rise beyond the limits of their worlds were True Selves, an eternal shackle to make them slaves to the Great Old Ones.
The idea of allowing something to interfere with his soul and bowing for all eternity to some creatures he had never seen before was something the black larva would never accept.
He was a black larva in the Physical Realm that controlled a Yellow Avatar in the Soul Realm, and he would rebel against entities that existed from the dawn of time.
Anyone would think the black larva couldn't succeed, but he did not care. He did not need others to believe in him. He only needed himself!
