Prologue: Echoes of the Past

Deep within the heart of the Shadow Realm, a forgotten darkness stirred. It had been centuries since this ancient force had last awakened, and the world above had all but forgotten its existence. But now, as the balance of power shifted with the fall of Lord Drath, the seals that had once contained this malevolent entity began to weaken.

The Abyss had always been a place of mystery and fear, a vast, seemingly bottomless chasm where the darkest energies of the Shadow Realm pooled. It was a place where even the most powerful demon lords dared not venture, for within its depths lay something far more dangerous than they could comprehend.

The ancient entity, whose name had been lost to the ages, was bound in a chamber at the very bottom of the Abyss. This chamber was not crafted by demon hands, but by a much older race—beings who had existed long before the demons had risen to power. These beings had been the original rulers of the Shadow Realm, wielding powers that even the current demon lords could only dream of.

But with great power came great arrogance, and these ancient rulers had believed themselves invincible. They had crafted weapons and artifacts of immense power, including the Harbinger’s Blade—a sword forged from the very essence of darkness. This Blade had been intended as a tool to maintain their rule, but it had instead become their downfall.

For the Blade was not just a weapon; it was a conduit for the entity’s power. The more it was used, the more the entity’s influence spread, until it had nearly consumed the entire Shadow Realm. Realizing their mistake too late, the ancient rulers had fought to seal the entity away, binding it within the deepest part of the Abyss. They had shattered the Blade and scattered its pieces across the realm, hoping to keep the entity from ever rising again.

But time is a fickle thing, and the seals began to weaken as the centuries passed. The demon lords, unaware of the true nature of the Abyss, fought amongst themselves for control, oblivious to the ancient threat that lay beneath their feet. When Malakar, and later Drath, fell in battle, the power vacuum created by their deaths sent shockwaves through the Shadow Realm. These shockwaves reached the very depths of the Abyss, causing the ancient seals to crack and falter.

The entity, long dormant, felt these cracks and began to stir. It was weak, far weaker than it had once been, but the power of the Harbinger’s Blade had begun to return to the world. Each use of the Blade, each drop of blood spilled in its name, fed the entity’s strength, allowing it to slowly push against its bindings.

In the darkness of its prison, the entity’s eyes opened—pits of pure shadow that absorbed all light. It could sense the world above, the growing chaos as the demon lords fought for supremacy and the humans struggled to survive. The entity knew that the time was nearing when it would be free once more, when it would rise and reclaim its dominion over the Shadow Realm.

But first, it needed the Blade.

The Harbinger’s Blade was the key to the entity’s freedom. The Blade had been reforged, and it had found a new wielder—a human, no less. The entity could feel the connection between itself and the Blade, a thread of dark energy that pulsed with every use. But the connection was incomplete; the human was resisting the Blade’s influence, preventing the entity from fully manifesting.

This human, Kuro, was an anomaly. He was neither fully demon nor fully human, but something in between—a shadow warrior caught between two worlds. The entity could sense the conflict within him, the struggle between light and darkness. It knew that Kuro was both its greatest obstacle and its greatest opportunity.

The entity reached out with its mind, probing the cracks in the seals, seeking a way to influence the world above. It could not yet break free, but it could whisper, could nudge events in the direction it desired. It could sow doubt, fear, and anger—emotions that would weaken Kuro’s resolve and bring him closer to the darkness.

Slowly, carefully, the entity began to weave its web. It sent out tendrils of dark energy, invisible to all but the most sensitive of beings, and began to manipulate the currents of power in the Shadow Realm. It whispered into the minds of the demon lords, stoking their greed and ambition. It fed the fears of the human soldiers, making them doubt their cause and their leaders.

And most of all, it reached out to Kuro, its mind touching his in subtle, insidious ways. It whispered to him in his dreams, planting seeds of doubt and fear. It showed him visions of a future where he succumbed to the Blade’s power, where he became the very Harbinger of Shadows that the prophecy foretold. It showed him a world consumed by darkness, a world where his friends and allies lay dead at his feet, victims of his own hand.

Kuro resisted, as the entity knew he would. But resistance only made the struggle more difficult, more draining. The entity could feel the cracks in Kuro’s psyche, the places where fear and guilt had taken root. It could feel the Blade’s influence growing, spreading like a cancer through Kuro’s soul.

The entity smiled—a smile that no one could see, a smile that carried the weight of millennia. It was patient. It had waited centuries for this moment, and it would wait a little longer if it meant ensuring its victory.

The world was on the brink of destruction, and the entity was content to let the pieces fall where they may. For in the end, all paths would lead to it, and when that moment came, it would be ready. It would rise.
