Chapter 1: The Abyss of Gehena
Hans Castillo Castillo was not always the monster spoken of in the prayers at dark altars, nor the specter that slinks through the whispers of ruined temples. There was a time when he was a man, a husband, a father, a friend… in short, an ordinary person. That quiet life ended the night a cult kidnapped him, chained him like a rabid beast, and threw him into the center of a circle drawn with dried blood and black earth. The stench of rusted iron mixed with the thick smoke of cheap incense clung to the walls of the underground chamber, relentlessly assaulting his senses. There, in that darkness, his calvary began.
Eszter was beside him, naked, chained at hands and feet. Blood flowed from multiple parts of her body while she remained dissociated from reality; her eyes were open, like broken mirrors that reflected nothing. Every prayer shouted by the fanatics was a knife sinking deeper into her delicate flesh. Hans was beaten with blessed rods, whipped with salt mixed with ash that made his wounds burn, but he said nothing and showed no sign of pain.
Seeing his wife lying on the floor, bleeding, a burning hatred was forged in his soul, a hatred that devoured everything he had once considered sacred. He observed every face marked by insane, putrid devotion, every gesture of false piety. And as the lashes fell on his skin and the pain of the soul filled him entirely, a certainty grew within him: if gods existed, they were silent accomplices to this slaughter, a slaughter he sensed was not the first his flock had endured.
His son was not there. He had managed to deliver him to a relative minutes before the cult stormed into their home, dragging them by force toward the sacrifice. The memory of his little Dylan Castillo was the only thread keeping him sane amidst such immense pain. Occasionally, a blow would snap him back to reality, shattering any hope, but also hardening him.
When he finally saw Eszter killed before his eyes, her body motionless, reduced to an empty sack on the stone floor, Hans ceased to be human. Something inside him broke irreparably, and at that moment, something else began to be born.
The cult, sated with blood and pain, left his body to a slow agony. They were convinced that his soul, stained by the blasphemy of the sacrifice, would be dragged without remedy into eternal punishment. And so it happened. Hans felt the detachment: his flesh fading, his heart marking its end in one last dry beat, consciousness sinking into a precipice of darkness. Then, the inevitable: darkness devoured him completely.
He awoke in Gehena.
There were no flames, no red devils with tridents, nor grotesque caricatures superstition invented to domesticate the living and keep them obedient. Gehena was the opposite: a realm of perpetual cold. An endless landscape of black rocks and broken towers, giving the impression of a wasteland drowned beneath oceans of ash and coal. The air was thick with lamentations, not human cries, but a constant, unlocatable murmur that seemed to rise from the ground, the walls, and nothingness itself. There, every step echoed like the condemned who would never again be remembered by the names they once bore in life.
Hans moved disoriented, feeling as if he were naked, though here the body was nothing but the memory of flesh taken in life. He felt no hunger, no thirst, only the unbearable weight of a memory that persisted beyond death. He knew he had entered the realm of the fallen, and that there was no way out.
Until he found it.
In the middle of a valley of cracked stones and under the shadow of a ruined tower, a colossus lay resting. It did not move, seeming to have slept for eternity. It was a demon diminished by the weight of time: Azrakel.
Its skin was dry and covered in mold, its horns broken, and its body streaked with cracks from which a faint, intermittent glow emanated, like embers that once burned fiercely but now agonized. Feared in remote eras, time had reduced it to a deep sleep, an endless slumber. Even the most powerful demons eventually succumb to the passage of time, and others take their place in the perpetual cycle of Gehena’s abyss. No one dared approach: even weakened by millennia, Azrakel radiated a latent power that kept the damned at bay.
Hans did not retreat upon seeing the sleeping colossus. He assumed no other condemned soul dared approach, for even in slumber, the demon imposed an impossible terror. He, however, approached until he stood before its stone chest. He felt no fear, only a burning curiosity. Hatred, pain, the loss of Eszter and his son had created something within him that no longer belonged to the world of men. His soul, instead of trembling before the infernal and the demonic, blazed with a force Gehena had never witnessed.
The demon opened one eye at his presence. A red glow burst forth, small but capable of devouring everything. At that instant, driven by an inexplicable impulse, an instinctive reflex, Hans lunged at the creature. He carried no chains, no weapons, only pure will and the naked decision not to yield. It was a clash against the impossible: an unspoken pact, a forbidden fusion.
For the first time in human history, since demons and men shared the same eras, the roles reversed: it was not the demon who possessed the man, but the man who took ownership of the demon.
Azrakel roared and shook its colossal body, trying to resist. The entire ground trembled; cracks in the stones widened, releasing columns of smoke and icy gusts. But Hans clung to the demon as one claims what is rightfully theirs. The man’s soul, blackened by loss, proved stronger than the exhausted eternity of the beast.
When the scream ended, there were no longer two. There was one.
Hans opened his eyes, and within them burned a double glow: human and demonic. An impossible amalgam, a hybrid that should not exist. It was a being that defied all laws, both natural and spiritual, a living fracture in the established order of the universe.
Then Gehena awakened.
The condemned felt it first, shuddering in their rusted chains. Then the demons perceived it, even those hiding in ruined towers and deep abysses. All raised their gaze toward the new presence. It was not man. It was not demon. It was something else. An aberration that did not fit the hellish design, a dissonant echo that shattered the harmony of eternal torment.
The first to approach was a high-ranking demon, with wings corroded by others and fangs like spears. It growled in challenge and lunged at Hans. But before it could even touch him, the darkness opened beneath its feet, swallowing it completely.
From nowhere, cracks appeared in the air, and colossal jaws emerged, with teeth as long as the demon’s wings. They were wolves: creatures of smoke and pure evil, with bodies forged in cursed mist, eyes incandescent like coals burning in absolute darkness. They tore through space itself and leapt upon the demon. Their howls were knives in the void. The jaws devoured it alive, eliciting a scream of agony that echoed endlessly, until nothing remained but the heavy silence of its disappearance.
Hans did not understand what he had summoned. It was pure survival instinct. The creatures—the Wolves of the Abyss—had responded to his will even without his conscious knowledge. As the jaws tore through, he felt a power no man had ever possessed.
The other demons who witnessed the event from afar recoiled. Not out of mercy. Not out of respect. They recoiled out of fear.
And hell fell silent.
Hans smiled for the first time since his soul was condemned to Gehena. A twisted smile, not of triumph or joy, but of arrogance. Something new had been born: the hybrid.
The demon, now also influencing his thoughts, revealed fragments of all the time it had ruled the abyss. It showed ancient secrets, memories of dominion and ruin, echoes of a power that once shook Gehena. In that vision, he understood a troubling truth: he could not remain there much longer. Not until he was fully conscious and capable of controlling this new body perfectly. His arrival had torn the calm of hell and drawn dark eyes; there were demons of extraordinary strength who would soon hunt him. He had to leave, and fast.
He remembered Eszter, his lost son. Now he had to return to the world… the world that had condemned him.
Hans’ eyes emitted the same red gleam that had shone in the demon before being subdued. Then, with an instinctive and brutal gesture, he tore the invisible fabric separating the planes. The fusion with Azrakel had granted him a gift reserved only for the highest-ranking demons. And so, passing through the rift in the darkness, he left Gehena.
Hans emerged on Earth as one awakens from a sepulchral dream. There were no glorious portals, no celestial fire; just a sudden change in the air. Gehena’s acrid stench dissolved into the night moisture of a forest. Trees stood in heavy silence, barely swaying in the breeze. The ground was covered with fallen dry leaves, and the full moon filtered silver rays through the branches.
For a few seconds, Hans believed he had awakened from a terrible nightmare. The touch of the earth, the murmur of a nearby river, the crunch of an owl in the distance gave the sense that everything was as before. But as he moved his hand, he noticed the shadow he cast stretched beyond the natural. Within his chest, a fire filled him with fury and a power impossible to ignore. He was not alone. Azrakel was still there.
The demon’s voice was still unclear in his head, more a constant murmur, a muffled echo creeping through his thoughts.
—This world belongs to me… you are only a guest—growled the beast from deep within.
Hans closed his eyes and laughed, just as in Gehena. It was not a man’s laugh, but the hybrid’s. And he had control.
—No. This world is mine now—he said firmly.
He began walking while assimilating everything that had happened. Each step made him more aware of his new nature. He discovered he could disappear into shadows or merge with them, vanish into the air as if invisible. Animals with the sharpest senses perceived him: a fox that crossed his path froze, paralyzed by instinctive terror, then fled in panic. Even the wind seemed to obey, vibrating as he passed.
But the most disconcerting was the first human encounter.
Peasants returning from their work, carrying sacks of firewood and lighting the night with torches, stopped when they saw him. Alone in the forest: a barefoot man in rags, eyes glowing as if on fire. One of them, perhaps the bravest, raised a torch and asked:
—Who goes there?
Hans did not answer. He just looked at them. And then he understood: his will alone was enough to sink into their minds and control them. A mere frown made the men tremble. One dropped the torch, another fell to his knees as if unable to hold his own body. He did not need to touch them; his mere presence bent them.
—Leave—he said in a voice that was not only his, but a deep, demonic echo.
The men fled, leaving behind the scent of their fear, which Hans could perceive in the air.
Azrakel laughed within him.
—Yes… this is how it begins. Make them crawl before you. They are livestock.
Hans stood still for a moment. He felt overwhelmed by this new reality. The power intoxicated him, but also unsettled him. It was not as simple as wielding a knife; it was knowing he could break wills, shatter minds, mold realities. Still, he knew he could not be consumed entirely. The demon awaited any gap to take control, and he was not willing to yield an inch. He was the mind, and Azrakel was the body.
He continued walking until the forest led him to a village. It was small: a few adobe houses, a small bell tower in the center, and fields stretching around it. From a hilltop, he observed. He could hear the villagers’ thoughts, scattered fragments: fear of drought, prayers, simple wishes to survive. Now all of it seemed insignificant.
Hans descended slowly. Each step was a test of mastery over himself and Azrakel. The shadows seemed to part to receive him. He felt power in every corner of his body.
A dog was the first to sense him. It ran barking, showing its teeth, but stopped abruptly; its back bristled, it whimpered, tucking its tail as it backed away as if it had seen something forbidden.
The doors of the houses began to open. Some women covered their children; the men grabbed tools as improvised weapons. The stranger before them did not seem human: ragged, barefoot, with a gaze from hell itself and a shadow enveloping his body.
Hans raised his hand in greeting. No one responded: fear had paralyzed them. It was a remote village, mostly peasants whose only schooling had been life. A supernatural stillness enveloped the street. Hans fixed his gaze on an elderly man who seemed to be the patriarch, leaning on his staff. Then he projected his voice directly into his mind:
—Do not fear. I have not come for you… yet.
The elder fell to his knees; the staff could not hold him, and he collapsed, mumbling prayers. The others followed, one by one, until the entire street was prostrate. Hans felt a surge of power flow through his body. He could dominate. He could reign.
It was a small village, and he wondered if this same submission could be imposed in a large city. Then he looked at his tattered clothes and, with a simple nod, transformed them into a flawless black suit, with a dark tie.
But something reminded him he could not stay. His memories of the past were not entirely clear; they arrived in small flashes that he pieced together like broken shards. He also knew—from Azrakel’s knowledge—that demons would hunt him. The weaker had trembled at his birth in Gehena, but the strong would not take long to cross over and destroy him. The unnatural hybridization had broken a balance established since the beginning of time, and soon they would come for him.
He walked among the kneeling villagers. None dared to look up; all felt a tremendous shiver through their bodies. It was as if a ghost passed. And, in a sense, he was.
At the edge of the village, he heard a sound different from the demon in his head. It was not Azrakel. It was something else. He perceived it distant, like a barely perceptible echo: brief howls, yet present.
—The Wolves of the Abyss—whispered Azrakel.
Feeling the great power of those invisible beasts shook him. It was the same manifestation that had arisen in Gehena. They were with him, latent, waiting.
Hans clenched his fists. He knew he had to learn to control these beasts before a stronger demon found them first. The Wolves were more than a weapon: they were the very essence of his power, his spearhead.
The path led him to a river surrounded by large stones. He leaned over the bank, and the reflection in the water returned a face he knew well, yet different: dark veins branched beneath the skin, and a faint red glowed in his eyes, giving him a demonic aspect. He was human, and at the same time, he was not. Hans Castillo Castillo had died in the sect’s torture chamber alongside his wife; what now stared back at him from the water was something else.
Azrakel spoke again, in a mocking and sarcastic tone:
“Look at you, fool… you think you dominate, but you’re nothing more than a child with a knife. I am eternal. I am the fire that burns in your veins. You will not resist me forever.”
Hans struck the water with his fist, erasing his reflection.
“Shut up. I am the one who possesses you, not the other way around. I am the master of my destiny; I hold the helm, and you are merely the ship.”
Silence returned. Azrakel knew he could do little against Hans’s strong soul.
That night, he slept among the roots of a giant oak. No animal approached him. He felt no cold, hunger, or fear. He dreamed of his son, his wife, of enormous wolves devouring not only bodies but memories, souls, and hopes. He dreamed that everything was swallowed by these hungry beasts… and he was at the center, like a king on his throne. Untouchable.
His human part, although no longer needing to eat or drink, still required sleep: the mental strain of maintaining the connection with the demon demanded recovery in this way. Azrakel, on the other hand, remained awake all night. It was an advantage: they could never be caught off guard. His senses were so sharp that no animal could match them. Upon waking, he understood something that would mark him forever: there was no turning back. He no longer sought redemption or justice. Only power. And with power, the ability to remake the world at will.
The hybrid had set foot on Earth and had no intention of stepping back for anyone.
Hans wandered for several days, testing his limits until his body fully obeyed him. He discovered that it no longer responded to human laws, except for the need to sleep. The sun passed through him without burning, the rain did not wet him. It was as if every element recognized him as foreign, as a crack in reality.
Azrakel’s murmur was ever-present. Sometimes he tempted him, sometimes insulted him, but Hans mastered him each time, taming him at will. The demon longed to break free, test his strength, reclaim control lost; but he contained him with pride, reminding him repeatedly that, for the first time in history, it was not a demon possessing a man, but the opposite, and he had no choice but to be its servant.
One night, a sound reached him, familiar yet unpleasant. He felt anger rising. It was some kind of temple, adorned with symbols of faith: wooden crosses on the large entrance doors, stained glass depicting saints and gods, and an altar. He hurried inside. Stepping in, he felt strange, as if the air itself had tensed around him.
Then he saw it: a circle painted in blood on the floor, within it a pentagram, and at its points, black candles flickering. In the center, a child, about to be sacrificed.
From the back of the temple emerged a group of men dressed in black robes. They carried crosses, daggers, and chains; their eyes gleamed with sickly sadism. It was a sect, one that toyed with people’s faith to kidnap them. They acted just like the sect that had killed him and his wife. Men spawned from the vilest depths of humanity. That was what had ignited his fury moments before. Hans recognized the latent danger in them.
“Tie him up too!” they shouted upon noticing his presence. “No one told you to stick your nose where it doesn’t belong, idiot… grab him!”
Hans raised his right eyebrow. His instinct urged him to laugh, but instead, he calmly stepped forward, walking straight toward them.
“‘Idiot,’ you say?” His voice echoed through every corner, a mix of human and demon. “Do you even know who you’re speaking to?”
The leader was the most fanatic of all; he realized Hans was not human. He lifted an iron cross, struggling to hold it upright; it was too heavy. Panting, barely able to utter words, he began reciting in Latin, some kind of exorcism. The words filled the empty nave, and his followers repeated them. Hans felt a slight burning on his skin, more irritation than pain.
Azrakel roared within him. “How dare they treat us like this? Let me out! Let me tear their flesh!”
Hans closed his eyes and let out a laugh that shook them all. The protective circle where they sought shelter glowed brightly, and for a moment, the hybrid felt the exorcism’s power trying to push him. But it was not enough.
“Nice show,” he said, his eyes glowing like embers. “But I am not a demon you can banish. I am something you cannot comprehend, and for your audacity, you will pay dearly.”
He advanced, crossing the circle effortlessly. The candle flames went out abruptly. The leader stepped back, incredulous. His followers raised their daggers, but their hands trembled uncontrollably.
Hans raised his right hand, and the shadows on the walls writhed like snakes. A wave of terror struck them like never before. One fell to his knees, crying; another dropped the dagger and tried to flee, but the doors were sealed, as was their fate. The leader tried to hold firm, murmuring prayers, until Hans looked him directly in the eyes.
Then it happened.
A darkness deeper than a night without stars or moon spread, covering every corner. It was not voluntary; it sprang instinctively, as if responding to Hans’s desire to destroy them. From the rift emerged immense, black, drooling jaws, pure malevolence. They were the Wolves of the Abyss.
The jaws devoured everything in a second, dragging it into the Abyssal void. All their bodies vanished without a trace.
Silence returned.
When the darkness faded, Hans, panting, surveyed the scene. He had not intended to summon the Wolves, but it had happened. The most feared power had manifested once again.
Azrakel laughed inside him. “Yes! That is the force that will make heavens and hell tremble! Use the Wolves, and nothing will stand in your way.”
Hans ignored him. He looked at the floor, where the child was chained. With a gesture, he woke him.
“Go back to your parents,” he said, his tone icy. “Tell them the Messenger of Gehena walks among the living and saved you.”
He walked to the nearly ruined altar. With his hand, he tore the remaining stone cross. He held it briefly, then let it fall.
“There are no gods here,” he whispered.
That night, far from the temple, he sat under a cloudy sky. Thunder rumbled, and Hans let the storm soak him. Everything had given him something to ponder: that enormous power, still manifesting instinctively and not by control, unsettled him. He also sensed movement beyond the horizon: demons seeking him, angels watching, humans fearing. And just as he could decide whether the rain touched him, he could choose to stay hidden or be found. The forbidden fusion had set the first turn of the wheel. It was just the beginning.
Azrakel, now in an almost soft, submissive tone, murmured:
“You’ve tested a bit of your strength. But you don’t yet know how much you can destroy. Soon, the truly powerful will come… and then you will see if you are the master, or just their prey.”
Hans closed his eyes, smiling cynically.
“Let them come.”
For the first time, he felt comfortable in his new body. He felt powerful. He was not Hans Castillo Castillo, the tortured man, nor Azrakel, the waning demon. He was an aberration, a hybrid. A king without a crown, but with a latent army in the shadows ready to act, speak, and desire.
Earth had received its new lord. And he was ready to claim it. Moreover, he had unfinished business and would not let anyone stop him.
The following days cemented the union, consolidating him as the absolute master of his choices. Hans discovered that everywhere he walked, shadows seemed to bow before him, as if the world itself recognized its new inhabitant and welcomed him.
Only the powerful decide their course; the rest think they do, unaware someone governs them from the shadows. He would be the ruler, not the ruled; the master, not the slave; the one who dictates the laws, not the one who obeys them.
Even the earth groaned beneath his step, unable to ignore the abyss he now carried. Even the fiercest animals recoiled.
Azrakel, though unable to take control, always whispered, trying to instill in Hans a demonic malice:
“We can rule them all, man. Humans, demons, angels, gods… none compare to what we are together.”
Hans barely smiled. He relished the demon’s pride but did not accept it.
“You are wrong,” he replied softly. “We are not two. We are one. And I decide.”
He had directed his path toward the city, though he could arrive there by disappearing into shadows. He preferred to continue walking; it pleased him. He came upon another village, more decadent than the previous, sunk in poverty. Muddy streets, adobe houses on the verge of collapse. Children stared at him with hollow, hungry eyes; mothers, with the resignation of those waiting for miracles that never come.
Hans stopped in the central square. Silence fell immediately. Disgusted by so much misery, he realized that although not entirely human, he was not indifferent to suffering. He had a son he loved, a wife he had loved. Nothing could change that, not even an army of demons.
A priest emerged from the village church, a sparse and crumbling construction barely standing. He carried a large crucifix hanging from his chest, almost disproportionate. Seeing Hans, the villagers clustered behind him as if seeking protection.
“Stranger!” said the priest with a trembling voice. “You bring darkness with you! I command you to leave this place!”
Hans looked at him calmly. A half-smile appeared on his lips, that pride that defined him. He walked toward him, unhurried.
“Darkness, you say, old man? I bring no darkness. I am the darkness.”
The priest raised the cross from his chest, lifted his face to the sky, and prayed. The hungry villagers did nothing but watch. Hans extended his hand, and with a barely perceptible gesture, the cross vanished. The priest let out a choked scream.
Hans inclined his head toward the villagers.
“I am just passing through. But know that the god you pray to will not come to save you. If you want to survive, do it alone.”
And he turned away. He only wanted to make it clear that their prayers were in vain, that no one but themselves could lift them from the misery into which faith had plunged them.
That same night, searching for a place to sleep in a forest clearing, he felt it. A pressure in the air, the temperature dropping sharply. These were not humans this time. They were demons. They approached with steps that shook the ground.
The first appeared among the trees: gigantic, black-skinned with twisted horns; on its face only a huge mouth.
“Azrakel,” the creature growled. “We finally found you.”
Hans rose calmly. He did not flinch even a little.
“I am not Azrakel. I am Hans. Nice to meet you.”
The demon laughed, showing fangs like swords.
“An aberration. It was true what we felt in Gehena. Then you will die as such.”
It lunged at him. Hans did not move. Instead, he let everything darken around him. For a moment, the forest vanished, leaving only an abyss of darkness. From that void, Hans emerged again.
He seized the demon by the throat. Surprised, it tried to retreat, but it was too late. With a brutal motion, he ripped off its head and, with a kick, threw the body into the abyss.
Hans lowered his hand with the dangling head, throwing it after the body. He was feeding his beasts. He did not need the Wolves: he wanted to test his own strength. They were still there, latent, waiting for their master’s command, but did nothing; he no longer summoned them by instinct. They only howled, approving their lord’s absolute control.
The forest returned, almost as before, except for the air heavy with terror. Azrakel roared with euphoria inside him.
“The Ereboros! Our shadow children are tamed! Something I could not do when I was only a demon! Now no one can stop us!”
Hans, breathing calmly, whispered:
“They are not yours. They are mine.”
With that demonstration, the rest of the demons stalking him vanished into the distance. His name began to spread. Soon everyone would know who he was: men and demons alike.
Days later, sitting at a tavern table in one of the villages near the city, he heard his name spoken for the first time.
“They say there is a man who walks like a shadow… he has been seen in several villages. They call him… the Messenger of Gehena.”
Hans smiled. He had given himself that name.
That night, sitting alone, he reflected. What would be the first thing he did upon reaching the city? Seek his son, or those who murdered his beloved Eszter? He thought of her: her soul must be tormented, just as his had been in Gehena.
He needed to set some objectives. He knew he was neither a hero nor a savior, but neither was he a villain. He was simply the one who broke the balance, the exception that defied the rule. He could build or destroy an entire city. And he would do so with the same calm, the same cynicism.
He looked toward the horizon, where the moon illuminated the night’s shadows. Azrakel’s voice spoke again, eager:
“Soon the angels will come. And men. And more demons. Most fear you, or fear the new. And what is feared, one wants to destroy. They will all want to destroy you.”
“I have nothing against anyone. But if someone wants to stand in my way, let them come. You will see them burn.”
The wind blew strong, lifting dead leaves from the trees. And that night, destiny was sealed: the world would no longer be the same. It would no longer be just heaven and hell. A force had been born that answered to none of them.
Hans Castillo Castillo, Azrakel, the hybrid, the ambiguous, the Messenger of Gehena.
And it was only the beginning.
