Cosmos, an intelligent being of an unquantifiable amount of power wandering in the empty and dark space devoid of time, was tired of the loneliness around it. It had been floating aimlessly without any knowledge of its origin. There was no beginning or end, just a limitless dark void.
One day it decided to do something about all the darkness in the space. It sacrificed its existence to create planets, stars, and dimensions. Thus begins the beginning of time. Cosmos died, but its power was scattered throughout his creations.
Soon new lifeforms formed on the empty planets. Countless races were born from nothingness. Among all those lifeforms, a human managed to harness a small fragment of Cosmos's power and made it his own. Thus born the first Creator. He utilized that power to evolve the human race and wanted to live in peace among his people.
Slowly more lifeforms from different dimensions got their hand on more fragments of Cosmos. Some failed to control it, while others succeeded and became Creators. But as time passed, the Creators, drunk in the Cosmos's power, waged war against each other, causing an unquantifiable level of destruction.
The first Creator who wanted nothing to do with this meaningless war got caught in the middle of the Creator's conflict. The war took away everything precious to him. While he was in deep slumber, the other Creators absorbed the evolved power of humans and made it their own. Everyone on his planet got reduced to dust.
When he woke up, the pain and suffering of his people flowed through his mind and heart. He went mad in rage and started to kill Creators, absorbing their power as his own. But, one day, he suddenly disappeared without leaving a single trace. By then, there were only 100 Creators left, and they decided to stop the meaningless fight.
However, it was too late. The one who created Cosmos caught wind of the situation and bound everyone who used Cosmos's fragments with an unbreakable restriction and appointed supreme beings called God to watch over the mortals. If the Creators were to use their power in the mortal realm, their existence would be reduced to nothingness.
Thus formed the realms of Heaven and Underworld.
Things didn't stop there. Some Gods got greedy and wanted to consume Cosmos's remaining fragments but couldn't get them themselves due to the restrictions. So, they used the Creator's power to unleash an apocalypse on the worlds that had traces of the fragments.
Little did they know that Cosmos had foreseen the future and created a plan of its own to prevent them before its death. It created a power that it was very familiar with, the infinite void. And a soul that is uncorrupted by the Creator or Supreme beings can only utilize it.
The wielder of the void is known as Void Walker. The corrupted Gods didn't know about the fact and sent two Creators to salvage the power of Cosmos on a small planet in the lowest realm. But, instead of the fragment, they found traces of a foreign power, millions of times more powerful than that of Cosmos, inside an unexplored realm.
They thought it would be a piece of cake but little did they know that their greed would be their end.
Their war with the lower realm awakened the first Void Walker, who killed the two Creators and isolated the lower realm along with the gateway of the undiscovered world within the void.
Still, today, Lucas, the first Void Walker, is hunting the corrupted ones while searching for the lost first Creator.
[Present Time] [Location: The fifth God's realm]
"Firstborn!!!!"
"What the heck is going on? First, that Void Walker lunatic, killing all supreme beings he finds, and now the Firstborn... Is this the beginning of the end?"
God of the Underworld yelled in shock.
"It must be the end... Or else why the heck would a Firstborn be there in the first place without my knowledge? And I tried to bless him, and you tried to take his soul on my order..."
"Haaa... In the end, we both lost everything because of my mistake. Well... Can't do anything about that anymore. It's better to assist him and go with the flow..."
God said after slumping back on the throne with a little sigh.
"Whatever..."
"But, don't forget... You owe me a big one..."
"When the time comes... I will make you pay for everything with interest..."
[Wooosh] God of the Underworld disappeared with a little gust of wind.
A couple of candles lit up brightly in the dark halls of heaven. God's eyes were shining with a golden hue as he looked toward the flickering light, "I will pay for my sins... But, for now... I must assist him on his journey with whatever power I have at my disposal." He muttered as his eyes fell on Ace, who was running toward Iris with a fearful expression.
"Waaaahhh!!!"
"You problematic brat... What the heck are you doing?"
God jumped up from his throne.
In God's realm, a couple of important things maintain the balance of life. First is the Well of Souls, where the dead souls get washed of the traces of their previous life and are sent to the Heavenly Gate.
Second is the Heavenly Gate, a massive white glowing gate where the washed and uncorrupted souls line up to receive God's blessing before rebirth.
The third is the Tree of Life. Its roots are connected with every living being on the planet under God's authority. It bears fruits on its roots, depicting successful rebirth. But when the balance of the world breaks, a fruit appears on its branch, depicting a soul that is born for the first time without God's influence. It's a rare occurrence that happened only thrice in the entire history of all Gods and supreme beings.
That lonely soul is called the Firstborn. They are resistant to God's influence and carry the misfortune of everyone around them on their shoulders. They bring happiness to others by sacrificing themselves and are destined to die at a young age since no soul can live without God's blessing.
God didn't notice the occurrence and tried to bless that soul. It backfired as, by that time, the Firstborn had already absorbed the misfortune of the souls around it. God lost his power momentarily, and within that small gap in time, the Firstborn's soul passed through the Heavenly Gate and was born on Earth as an unlucky boy chased by misfortune.
