Chapter: Veil of Pestilence

“Where sickness spreads, courage must endure”

In the shadow of the Black Death, a masked doctor wandered the plague-ridden streets of Firenze, spreading both fear and fascination. Known only as The Plague Doctor, Niccolo Vieri vanished into the mass graves of the afflicted, leaving only whispers of his “treatments.” Now, drawn by the Entity, he roams a realm where death and disease intertwine, seeking fresh subjects for his morbid experiments.

Opposing him is Alessandra Rossi, a healer hardened by tragedy. She witnessed the doctor’s cruelty firsthand and refuses to let him claim any more lives. Her courage fuels her allies, and her determination turns the tide against the creeping sickness.

Face the spread of disease and the shadow of death in the Veil of Pestilence, where survival demands both teamwork and resilience.

Dr. Niccolo Vieri – The Plague Doctor

Born in 1318 in Firenze, Italy, Niccolo Vieri was the scion of a family of learned medicinal scholars. When the Black Death swept across Europe in 1347, Vieri became one of the first to volunteer as a physician, and remained a well known Doctor, becoming moderately famous for his miraculous remedies. Clad in the beaked mask, waxed coat, and wide-brimmed hat that would become his chilling signature, he ventured into the homes of the dying, his hands steady even as death clawed at him from every side.


Yet repeated exposure over the years to the plague left its mark. Vieri fell ill, but rather than succumb, he found in the sickness a grotesque clarity. Life, death, flesh, and decay revealed themselves in sharp relief. He began experiments that twisted medicine into monstrosity, at times even on himself, learning to command the plague itself, sustaining himself in a state of perpetual infection, thus becoming the very sickness he once cured. Though he was able to keep most of his body in this state, Vieri would experience pain and agony with every step, every breath. Death became a companion, the sickness a crucible — and through it, Vieri sought to achieve true purification.


To him, the plague was not calamity — it was revelation. The screams of the dying became progress, their decay a lesson in the fragility of flesh. The “cured” were only delayed; the purified were those who had embraced suffering. Some unfortunate patients would writhe as the plague consumed them, only for Vieri to reverse its effects, then strike them with the disease anew. Their skin would bloom with putrid green spores, a grotesque signature of his experimentations. None survived.


Whispers of his deeds spread through Firenze: the doctor who courted death, who wandered plague pits at night, muttering calculations of contagion. His colleagues recoiled in horror upon seeing his victims; his family repudiated him. Soldiers eventually came to seize him, but Vieri and his experiments vanished into the rolling Tuscan hills.


They said that after months of searching, they finally cornered him near a field of mass graves, a ghostly gray fog tinged with sickly green rose around him. Vieri’s voice, calm and unwavering, declared that perfection was near. Then, as if swallowed by the plague itself, he stepped into the mist — and vanished. No trace of him, no sign of the glowing fog, remained.


The Entity welcomed him. In its realm lay a world of endless suffering and decay, Vieri found a laboratory unbound by mortality, unshackled by weak morality. Here, the sick never truly die. Here, the living are prey, the dying subjects of his experiments. Every scream furthers his understanding, every suffering body another brushstroke in his grotesque masterpiece. Behind the luminous green glass of his mask, Niccolo Vieri watches, unblinking, awaiting the next soul to be purified.


Alessandra Rossi – Survivor Counterpart

Born in 1329 in Firenze, Alessandra Rossi was the daughter of a tailor and a midwife. From an early age, her hands were always busy tending the sick, bathing fevered foreheads, bandaging festering wounds, and burying those who could not be saved during the Black Death. Death was common, hope was not. 

Nevertheless, when rumours spread of a masked doctor whose methods defied all reason, Alessandra’s family sought him desperately to save her brother. Niccolo Vieri arrived, his mask glinting in the candle light, a long cane tapping against the floor as he muttered under his breath about the nature of disease. Vieri closed the door behind him, trapping his victim to his fate. What was once Alessandra’s greatest hope became their greatest fear. When she entered the room to inspect what the treatments were, the horror was revealed. Her brother lay dead, covered in glowing green flowers and spores. The doctor was nowhere to be seen, even though Alessandra couldn’t see him she swore she heard the walls whisper that the sickness was “incomplete”. 


Haunted by grief and suspicion, she tracked Vieri’s experiments across the countryside, witnessing horrors that twisted her stomach: shrieking patients, grief stricken families, bloated corpses, skin crawling with green pustules. Each encounter confirmed her dread — he did not heal; he toyed, he studied, he destroyed. Determined to stop him, Alessandra enlisted soldiers to hunt the Doctor. But he fled, leaving only chaos in his wake. She was left to gather the remnants of his cruel experiments, the echoes of suffering a bitter weight on her conscience.


Weeks later, she awoke not in Firenze, but in a world drenched in fog and the scent of rot. Screams of the tormented hung in the air like smog. And there, gliding through the green haze, was him — the Plague Doctor, his mask gleaming, passing through walls, ever searching for new subjects.

Alessandra swore she would save any she could, no matter the cost. She could not stop the horror entirely, but she would bear witness, she would fight, and she would endure — even in a world where death was only the beginning.
