He was once a conqueror. Now he returns—to reclaim his power, his lovers, and his destiny.

Have you ever wondered what would happen if a man with boundless ambition were given the chance to turn his dreams into reality?

When fate aligned, one such man—a visionary from our world, gifted in both science and art—was cast into a realm of magic, danger, and desire.

Armed with intellect, ambition, and dark charisma, he learned to blend the logic of science with the chaos of sorcery. 

With this new power, he crushed kingdoms, seduced mistresses, and forged an empire in the shadows. Under the name Shadow, he and his order—the Twilight Shadows—extended their reach across the continent, infiltrating every corner of society.

His loyal companions stood beside him: the ruthless warlord, the divine accountant, the graceful actress, and the merciful healer—each bound by devotion and desire. 

Together, they conquered the world. But even absolute power couldn’t fill the void within his soul.

In search of meaning, Shadow withdrew into a long, enchanted sleep, entrusting his empire to his followers. Yet power corrupts, and loyalty fades. His dominion fractured. His name became legend.

Now, centuries later, Shadow awakens to a world forever changed—and a rising threat known as Betrayal.

His allies are distant. His enemies are stronger than ever. And something deeply precious has been stolen from him.

Once again, the conqueror must rise from the darkness. 

Will he rebuild his empire, reclaim the hearts of his forsaken companions—and bend the world to his will once more?

Penelope Campi

A kind and compassionate young woman with a sharp sense of justice. The altruism in her heart often leads Penelope into trouble — people tend to take advantage of her good nature. Yet her care for others comes from something far deeper, something almost innate. When her gaze falls upon the Shadow, her eyes shine with pure joy.

Katarina Superbia

An arrogant, proud actress whose dreams are fixed upon ever-greater fame. Behind her dazzling facade lie deep wounds and hidden insecurities. She can be unbearable at times — yet when put in her place, her defiance fades, and a gentler, obedient side emerges…

Anita Floras

A genius of mathematics — calm, calculating, and methodical in her every move. Gifted in all things concerning finance and economics. Once, she held firm principles… but traded them away for wealth and recognition. Now, burdened by guilt, she seeks to punish herself — awaiting the day she meets her true master once again.

Varanetta Bartende

A wanton, audacious woman, consumed by insatiable desires and a craving for bliss. Once a great commander — a general of the mighty order that led thousands of legions in the grand wars for world dominion. Now, she indulges in her favorite pastime: “draining” her personal guard to the last drop. None have yet survived the ordeal to grant her true satisfaction.
Legend whispers that only one stranger ever succeeded…
