My World Traveling System: The Harbinger Of Death

-----

Chaos.

A mere name he gave to himself. He was born as two entities from the darkness accumulated within Earth over hundreds if not thousands of years.

Once, Earth was overrun by monsters that covered the world, in the medieval times and even before that, adventurers and knights commonly fought monsters that threatened Kingdoms and provinces.

Within this dark era, the miasma of the planet Earth continued to grow stronger, and from within this darkness, in the depths of the center of the world. A fragment of somebody fell from outer space, reaching these deeps like a meteor.

BOOOOMMM!!!

The enormous explosion shook the Earth, even Gaia felt worried that such a big meteor had suddenly fallen over her surface, seeping deep underground, but quickly forgot about it… she committed a grave mistake.

This meteor held a crystalized soul piece from a being that was once defeated by someone… Frank's father, specifically. Although this being had managed to also weaken his father and seal him away, he ended tearing apart into pieces that fell across the cosmos.

Interestingly enough, a large piece of it fell into Earth, crystalized into a meteor. The darkness and miasma generated in the surface of the planet due to the corruption of the rich mana flowing all across ended being feed into this soul fragment… or fragments.

Indeed, it was but two pieces originally, which were then reborn as two… strange creature. At first, they resembled monstrous beings made of dark goo, crawling out of their hole for years until they finally reached the surface.

The first thing they saw were monsters everywhere, and without questions they began to devour everything. Somehow, they knew both were "siblings" and did not killed one another, but cooperated, sometimes even sharing meals when the other had not managed to catch prey at the end of the day.

Over years, they traveled across the vast lands of Europe, reaching into a village of people… and massacring it. They without a sheer of a doubt devoured every person inside, acquiring the intelligence of humans, emotions, and even their memories.

They learned about malice and good will but felt that emotions… were somehow disgusting. They tried to reject them and deny them, as they continued devouring everything.

Eventually, they became a threat that was said to be a calamity, known as the "Demon King". In these ancient times, a group of knights who had grown exceedingly strong by slaying monsters and acquiring their magic power through special techniques taught to them by the monastery of god in those times went into a crusade to slay the Demon King, an enormous mass of black slime said to devour anything.

Eventually, the two were somehow defeated by the knights, although they faked their deaths and escaped. They learned that were stronger beings out there that they couldn't challenge yet, and eventually, they learned to merge with human's society and find easy prey by deceiving.

<br/>"Humans are so stupid, how easy it is to deceive them!"

"We must continue devouring more humans, we'll defeat those knights eventually! Ooh, I can't wait to feast on them!"

They were quite simple minded… however, as they continued feasting on humans, the world changed and shifted, they were forced to adapt alongiside the humans. They were sometimes forced to move away and traveled the world around. they fought many monsters and met even gods, they tried to devour gods, but ultimately failed miserably.

But they were a stubborn pair. Over time they built up an organization, thinking that by imitating the humans, more tasty and stronger humans could eb attained. Over time, their simplistic way of thinking evolved more complexity, and alongside that, memories of what they used to be began to flow across their minds, eventually, they realized they were not mere and strange monsters.

After having realized the knights that once defeated them died long ago, they decided to move over and adapt to humans and their organizations, learning more and growing more ambitious as they learned the truth about everything. Eventually, voices began to speak into their minds as they learned about their other parts. Beings that were also the same being they were once before.

Together with them, they set up a plan to finally meet with one another through what was called world convergence. The twins could had been able to open the gates if they acquired the Source, an enormous concentration of energy that the planet Earth was saving, which ended slipping off their grasp and falling into Frank… which ended causing all of the story until now.

Using the Chaos Gate as an organization to intimidate the world which also allowed them to pick up tasty meals and experiment into creating new and tastier meals, they continued growing stronger until this day… Although they had done many things, their minds were rather simplistic, and usually, they merged together as one as they felt comfortable this way.

Their original plan was to actually shatter the Earth's core by draining all her energy, so they would be able to devour the entire planet and gain enormous power, after that, they would end up traveling across the Universe seeking more things to devour… unlike the Emperor and the others, they were simple minded until the end, and perhaps this was the reason why they acted so childishly and edgy.

And now, they were confronted by the other selves from other worlds, but they rejected the idea of merging themselves into one of them, as that would be like dying and sacrificing themselves… discussing so much ended making them lower their guard. And now, the one they always hated and sought after because he took their Source from them had trapped them within a large room inside a Dimensional Dungeon, and as if they were a mere Boss Monster inside a game, he planned to slay them here.

"Is this your big scheme and plan? Closing ourselves inside a room so we can kill each other swiftly?" He laughed. "Well, let me summon a friend as well, I am sure you know him well…"
