Far away, in the depths of a world that exists just beyond mortal perception, there existed an ancient and malevolent being named Mammon. He was a demon, a prince of darkness, a ruler of greed and corruption, and yet, as much as his name was feared, it was also whispered with a certain reverence. Mammon had long been obsessed with one thing - power. The kind of power that could rival even the gods themselves. And to obtain it, he had spent centuries searching for an artifact, a relic so potent it could reshape the fabric of existence.
This artifact was called the Heart of Vaal, a jewel rumored to be imbued with the souls of fallen angels and the wrath of the underworld. It was said to grant its wielder the ability to command not only the infernal legions but also bend time, space, and reality to their will. However, the Heart had been lost to time, hidden away in a place no mortal or demon dared to tread: the cursed ruins of Nethru, a city swallowed by the earth after the betrayal of its own rulers.

Malthus looms large in the fog, an imposing figure with huge eyes and formidable horns, evoking an ancient majesty intertwined with the mysteries of the unknown.
Mammon had heard whispers of it, felt its pull across dimensions, and knew it was within reach. But others were aware of its existence too. In the shadows, a cult known as the Seekers of the Black Flame had risen, hell-bent on claiming the Heart for themselves. They were led by a powerful sorcerer known only as Zephar, a man who had once been a mortal, but now, after years of forbidden rituals, had become a twisted vessel of dark energy.
The rumors of the Seekers' attempts to claim the Heart had reached Mammon's ears through the whispers of demons that served him, and for the first time in millennia, Mammon found himself in a race - not just against time, but against other beings of darkness. He could not allow such a power to fall into the hands of mortals, especially those who were nothing but pawns in a larger game. The Heart was his birthright.
As Mammon traversed the barren wastelands towards Nethru, he could feel the weight of the curse that hung over the city. The air was thick with despair, and the earth itself seemed to hum with malevolent energy. Shadows slithered in the corners of his vision, fleeting and intangible, yet unmistakable in their presence. He had been here before, centuries ago, when the city fell. But now, it was something else entirely. It was a place caught between worlds, a place where the dead whispered to those foolish enough to listen.
He approached the heart of Nethru, where the ruins of the ancient temple stood. The ground was cracked and blackened, the remnants of a once-glorious city now reduced to a crumbling skeleton. As he entered the temple, the air grew colder, and the faintest sound of chanting reached his ears. Zephar and his cultists had already arrived.
Mammon's eyes glowed with an otherworldly light as he stepped into the grand chamber of the temple. At its center, surrounded by arcane symbols and glowing runes, lay the Heart of Vaal. It shimmered with an unnatural brilliance, its surface swirling with dark energy. Zephar stood before it, his hands outstretched as he chanted in an ancient language, his eyes alight with the madness of power.
"You are too late, Mammon," Zephar hissed, his voice echoing off the stone walls. "The Heart is mine. Soon, all of creation will bow to me."
Mammon smirked, his voice low and cruel. "You think you can control that power, mortal? The Heart of Vaal doesn't belong to you. It was always meant for me."
Zephar's lips curled into a snarl. "Then come, demon. Let us see if you can claim what you believe is yours."
In an instant, Mammon lunged forward, his form shifting into a mass of shadow and flame. The cultists screamed in terror, but they were too weak to stand against him. Mammon's power was overwhelming, each strike of his hand sending blasts of fiery darkness that obliterated the walls around them. Zephar, however, was no mere mortal. He was a being of dark magic, and he retaliated with bolts of crackling energy that cut through the air.

In a fairytale-like garden, Malthus dazzles with enormous wings, surrounded by colorful mushrooms, conveying an enchanting aura, while a playful companion adds charm to the moment.
For a moment, Mammon faltered. He could feel the Heart's power beginning to resonate with his own, testing his resolve, his strength. Zephar's spellwork was formidable, but Mammon's essence was born of the abyss itself - far older and far more dangerous than any mortal wizard could ever hope to be.
With a roar, Mammon shattered Zephar's shield of dark energy and grabbed him by the throat, lifting him off the ground. The cultists attempted to intervene, but Mammon's mere presence was enough to send them fleeing in terror. Zephar gasped for breath, his eyes wide with fear.
"Do you know what you have done?" Mammon snarled, his grip tightening. "You meddle with forces you cannot understand."
Zephar's face twisted into a grin, even as his life slipped away. "I am not afraid of death, demon. The Heart is already mine. You cannot stop it."
But just as Mammon was about to deliver the final blow, something strange happened. The Heart of Vaal pulsed with an unearthly energy, and Mammon felt a surge of power unlike anything he had ever experienced. For a brief moment, his vision blurred, and the world around him seemed to stretch and bend, as if the very fabric of reality was unraveling.
Then, the Heart's power took hold.
Mammon had never felt such strength before. It was as if the very universe had bent to his will. But with this new power came an overwhelming sense of unease, as if he was no longer in control. The Heart was not an object to be wielded - it was a force unto itself, a sentient thing that had its own desires, its own will.
In that moment of realization, Mammon understood. He had been a fool. The Heart was not a tool for domination - it was a prison, and he was the one who had been trapped. The very essence of the Heart twisted, binding Mammon to its will, and for the first time in his long existence, he felt fear.
As the ruins of Nethru began to collapse around him, Mammon screamed in fury, his form dissipating into shadow as the Heart's power consumed him, its whispers echoing in his mind.

Emerging from the mist, Mammon captures attention with his vast wings and enigmatic presence, embodying the complex tales of wealth, power, and the quest for desires long held.
He had sought power, but in the end, it was power that destroyed him.
And the Heart of Vaal, once more, was left alone in the ruins, waiting for the next soul foolish enough to seek it.
The world continued its endless cycle, and the name Mammon became but a distant memory, whispered only in the darkest corners of the earth, a warning to those who dared seek the Heart of Vaal.
