On this continent, humanity was but a speck of dust in an infinite world—brimming with potential yet terrifyingly fragile. Settled at the heart of the land, humans built their civilizations, striving to grow stronger, desperate to carve out a place in this vast and boundless realm. Yet the continent’s secrets, dangers, horrors, and ancient powers dwarfed human imagination.

Civilization huddled within borders ringed by places called **No Man’s Lands**—zones marked as Adventure Maps on charts, territories where humans dared not tread.

Fear sprang from the unknown. The unknown bred ignorance. And ignorance meant death.

Still, human greed and curiosity knew no bounds. Those who made a living exploring No Man’s Lands were dubbed **Suicide Squads**—adventurers branded by the world as both the stupidest and bravest souls alive.

The reason was simple: No Man’s Lands belonged not to humans, but to gods.

This world predated humanity by eons. And some beings here predated the world itself.

Before continents formed, before sky and earth split apart, when all matter swirled in chaotic void—humans called that era the **Ancient World**.

When the world reshaped itself, birthing land and sky, those primordial entities survived.

The **Ancient World True Gods**—Hidden Bosses of the world—were the oldest, most powerful beings on the continent. They existed long before humans crawled from the mud. Their power could erase human civilization with a flick of a wrist.

True Gods wore forms beyond human comprehension—bodies forged from alien matter. They might appear as a wolf one moment, a dragon the next, or even a human. Their shapes shifted like smoke. Omniscient and omnipotent, they commanded cosmic forces, seeing past and future alike.

True Gods acted on whims. They commanded faith, gathered followers, and held life and death in their palms. Yet bound by the **Primordial Covenant**, most remained confined to their own No Man’s Lands, barred from directly erasing humanity.

**World False Gods**—Map Bosses of the realm—were equally ancient and mighty. Unlike True Gods, they remained bound by biology: the oldest, strongest creatures alive. A deep-sea leviathan. A mountain giant. One form. One existence.

They lacked the omniscience of True Gods. Some possessed wisdom; others moved on instinct alone. Yet their power was undeniable.

The Primordial Covenant trapped them too within their No Man’s Lands. But without wisdom to guide them, some strayed—threatening human civilization.

Then came the **Plague Deity**—an Outsider from beyond stars. Humans believed them alien invaders seeking conquest.

More enigmatic and lethal than True Gods, Plague Deities saw humans as prey and playthings. True Gods might spare lives on a whim; Plague Deities never did.

Their forms defied reason. Biological yet spiritual, they might manifest as mist, a bone, writhing tentacles, a rusted blade, a slab of meat, or tattered cloth. They wore existence itself like a cloak.

Their intellect might even surpass the omniscient True Gods. When encountering humans, Plague Deities offered only two fates: annihilation or amusement. They hunted for profit or pleasure—tempting, cursing, possessing, deceiving, devouring. Or **Assimilation**.

**Assimilation** was their most terrifying power—and the core of their invasion doctrine. Beyond unique abilities, all Plague Deities wielded psychic assaults. Victims first hallucinated, then raved, finally twisting into thralls: slaves, servants, sub-species, **Thralls of the Plague Deity**.

Becoming a Thrall meant losing one’s race, freedom, even mind—reduced to an empty shell under the Deity’s will. Bound by the Primordial Covenant, Plague Deities remained trapped in their Hidden Maps. Yet humans could summon their avatars through forbidden altars.

Thralls were humanity’s sworn enemies. Unbound by the Covenant, they raided settlements near No Man’s Lands. They couldn’t penetrate deep into human territory—their power faded far from their Deity. But exceptions always existed.

The **Primordial Covenant**, legend said, was forged between the ancient **Human Emperor** and the elder gods. Its terms remained secret.

Its core decree: elder gods could not directly extinguish humanity.

Yet in a world of infinite wonders, exceptions always existed…

And you? You were about to step into this world as a brave adventurer.
