My World Traveling System: The Harbinger Of Death

-----

Within the depths of Terra's underground, an enormous, gargantuan entity rested, slowly yet steadily growing large and larger… readying itself to finally emerge out of its shell, the planet's surface, and finally free itself from this enormous sea of miasma that both gave birth to it and that is also imprisoning it.

The entity's mind began to flow with constant information of previous generations, as it was made of their same miasma, it inherited their memories and powers.

Every generation, the entity would become even stronger and deadlier.

But at some turning point in the previous generation, something else got mixed in with the miasma, the will, and soul of a strong Magus, which merged itself with the main Miasma Soul that composed the entity for many generations.

Of course, the entity had killed many Magus before and wiped out entire Eras of powerful experts like nothing, but it had never experienced this type of soul fusion before, and these Magus souls were always sent to the transmigration cycle after dying.

However, this time, it had turned out different.

Almost 100.000 Years ago, in the last decisive battle against the Demon King or the Chaos Child, the Heroes gave their life to damage their Miasma Soul and finally let the beast rest once more.

Every generation, Heroes always found ways to break the Miasma Soul.

Like glass, it would shatter into pieces, and the Demon King would simply turn into a lifeless puddle of miasma.

However, this soul was immortal, and although it was shattered, it quickly merged back up, even stronger than before.

Each time it was shattered, it regenerated even bigger and stronger, and the entity became even deadlier.

This entity was a constant, and monstrous reminder to all mortals of the mistake of the Gods, of their lack of experience in creating a world, and of their rashness of making one without proper preparation.

Axitl was also a reminder, as she and the Demon King were born similarly, from the same source, but with different fates and destinies, yet Axitl found that the Demon King was perhaps not as different as her, and she even considered it her sibling.

However, this new generation was different than any other.

Almost 100.000 Years ago, when the Heroes gave their lives to defeat the Demon King, the Elven Heroine, the Heroine of Elemental Spirits used a forbidden spell that used her very soul as a weapon, inflating it like a balloon and giving her the most painful of deaths in exchange for finally defeating the Demon King.

She had used such technique as a last resort when all other Heroes died, and she was the only survivor…

In that time, she had decided to carry in the burdens of all the innocents that died because of her foolishness, and took her like and used it as the deadliest weapon.

When her soul exploded, enough damage was finally deal and the Miasma Soul shattered once more.

However, instead of going back to the Transmigration Cycle, the Soul of the Heroine explored and shattered, mixing with the Miasma Soul of the Demon King in the process.

Unknowingly by many, a Heroine's soul fused with the Demon King's soul after both of their death.

And now, the entity of this generation, the Demon King, the Chaos Child, was slowly regaining the fragmented memories of its past lives and the Heroine…

All of it merged together into a single entity, and consciousness finally emerged, alongside intelligence as it had never possessed before.

It questioned itself, asking itself many things at first.

The memories it had seemed not his, yet incredibly familiar.

"Who am I?"

"What am I?

"What am I doing?"

"Where am I?"

It kept questioning the world and why things were as they were.

It began to feel uncomfortable, to feel as if things were not right, that things seemed strange.

This entity born from the soul of the heroine and the demon king was not any of them, but someone completely new, tormented by fragmented and warped memories of lives it shouldn't see.

However, thanks to such memories it had consciousness, intelligence, and complex thoughts.

But…

What was it at the end?

What was its purpose?

It questioned many things but… what should it do now?

"Am I… a Heroine? No… I am not… her…"

"Was I a monster? No… I am not… the monster…"

"What… am I?"

For the first time in the history of Terra, the Demon King, often named the Chaos Child by the Demon Folk, acquired complete consciousness, sense of self, intelligence, and complex thought processing.

The entity questioned the world and sought answers that the warped and fragmented memories could not offer.

It tried to seek such answers as it delved into the memories, but the more it delved, the more chaotic everything seemed…

There was no way out of this other than to seek answers of its existence and purpose than to escape the eternal darkness it existed within, alongside the sticky and incredibly heavy sea of pure miasma where it was born.

The more the entity tried to escape, the more fragments of itself it would divide, which would seek what it originally wanted, to reach the surface.

However, such smaller fragments didn't possess intelligence and were chaotic and savage, and seek food to sustain their fading existences, looking for any large signal of mana around the world.

This is why Abyssal Horrors would often spawn near big cities or dungeons, as such places held many living beings filled with Mana, making for great food sources.

The Demon King kept struggling, it kept trying to escape its prison, slowly… yet steadily, its large, monstrous claws began to naturally swim through the miasma, a natural disaster so immense it shock the planet with each step…

Slowly, it was near the shores of the sea, and it would keep walking until it could find light and the surface, using the memories and intelligence it was gifted with to seek answers and a purpose, unaware that its very existence could endanger all life.

Unknown to it, its purpose was to only bring destruction and chaos and could not be changed.
