Chapter One: The Primeval Era

Thirty million years ago, the universe was utterly unlike anything known to humankind today. Yet such a magnificent era has forever been buried and forgotten beneath the dust of history. In those ancient times, the universe had but one true center—Earth.

Earth was immense beyond imagination, dwarfing even the Star of Ultraman in its scale. Humanity thrived as the dominant species upon its vast surface. Though physically frail, humans possessed remarkable intelligence, and with their wisdom, they developed a level of technology far beyond what exists today. Yet progress was not instantaneous; technology was forged slowly over the ages, shaped by the relentless march of time.

Back then, humanity had not yet achieved the means to defend themselves. Living in tribal societies, they faced grave threats—creatures that seemed like their natural nemeses: monsters.

Legend held that these monsters were creations of the universe’s first darkness, brought forth by the primordial god of darkness, Emperor Karafal. It was said that this deity dwelled in the endless shadows of the cosmos, or perhaps he was the very source of darkness itself. More adept at creation than at battle, his most indifferent inventions were the monsters. Their forms were bizarre and unsettling, for Emperor Karafal had fashioned them without any care or purpose.

Despite their strangeness, the monsters shared certain common traits: most stood forty to fifty meters tall, clad in tough, armored skin, their faces twisted and ferocious. Some could fly, others spewed fire or energy from their gaping maws. To them, humans were food—small, tender, and succulent, the perfect delicacy for their monstrous appetites.

Driven to the brink of extinction, humanity resolved to seek refuge in the vast, unexplored regions of Earth, hoping to escape the monsters’ relentless predation. They braved the seas, and, after a tempestuous voyage, arrived at a new continent—or perhaps a vast island—never before touched by human feet.

This place was called Lulue.

Lulue seemed a paradise suspended across the ocean, untouched by monsters or calamity—a haven for humanity. Yet there were natives living there.

These natives existed in a peculiar form: light.

They lived entirely as beings of light, possessing consciousness without physical bodies, mere clusters of radiant energy. Drawing sustenance from ambient light, they feared the darkness—for in darkness, they would weaken and perish. This characteristic made them natural adversaries of darkness. Whenever night fell, they would inhabit small stones known as Lightstones, which emitted their own gentle glow, perhaps a form of unique crystal.

Upon seeing humans, the beings of light regarded them with hope and envy. Humans possessed limbs, flesh and blood, eyes, mouths, noses… Most importantly, they did not vanish when darkness came, never swallowed by night. In every way, humans appeared to be nature’s most perfect creation.

The beings of light welcomed humanity, offering acceptance, but requested basic assistance in return—construction, maintenance, and other tasks impossible for their incorporeal forms. As exchange, the light beings offered protection and pledged to annihilate the monsters for humankind. Thus, a friendly pact was forged: humans would provide bodies for the light to inhabit and fight with, while the light beings would reside in small, special containers, never interfering with human choices or daily life. Only in times of battle would they briefly take control of the bodies to engage in combat with their own consciousness.

For this union, a medium was required—the crystal Lightstone in which the light resided.

Those who accepted the terms of the light and met the criteria were called Agents.

When the first Agent merged with the light, all humankind wept for joy. At last, hope shone through the endless darkness. That first Agent, fused with light, towered above even the mountains—over fifty meters tall—his form streamlined and elegant, blue and red swirling across his skin, his eyes gleaming with milky radiance, a deep blue energy timer glowing upon his chest. He soared freely through the skies, unleashed powerful energy beams, and could destroy an entire mountain with ease.

Such beings were called Ancient Gods.

Thus, the relationship among humans, light, and monsters was established. Under the protection of the Ancient Gods, humanity’s numbers grew anew, and technological progress soared. The goddess of hope once again showered her radiance upon Earth. Though monsters still ravaged parts of the continent, with the Ancient Gods’ shelter, humanity brimmed with hope.

Yet, amidst this resurgence, an evil power began to rise. This force was composed mostly of beings who had shed their beastly instincts and attained high intelligence, yet were wicked at heart. Each was extraordinarily powerful, calling themselves the Old Ones, and their followers were known as Servants. The entities they worshipped rarely appeared, for their numbers were few. Confronted by the alliance of humans and light, and by the Ancient Gods, they resorted to creating weapons.

By luring those with twisted intentions, they transformed them into devout Followers. Through these Followers, they kidnapped children from various tribes across the continent, subjecting them from an early age to modification and indoctrination, making them willingly become Sacrifices—remade as weapons, akin to the Ancient Gods.

These beings, modeled after the Ancient Gods, bore similar forms, yet their skin was cloaked in darkness. Brutal and destructive, they once slaughtered the humans of an entire continent, remaking it as their playground, which became known as the Dark Continent.

Such terrifying entities were called Evil Gods.
