Greymoor City never truly sleeps.Not really.At night, when the lights dim and the streets seem to inhale, something wakes in the narrow alleys-something that listens, weighs, and measures every wound, every wrong turn, every unspoken wish.It's during these hours that the Iridian Apothecary appears.A pharmacy with no address, no listed hours, no public existence.It opens only after midnight.It doesn't sell medicine.It sells impossible solutions-remedies for things no doctor can diagnose: broken memories, lingering grief, the hollow places left by trauma.Every cure works.Every cure has a price.And the price is always personal.Lena Morrell, a sharp, skeptical journalist, believes only in what she can verify. But when Greymoor begins to reveal a version of itself that no one else sees-when a terrified runner speaks of a cure that helped him and hurt him, when a door appears where nothing existed, when the city itself seems to lean toward her-Lena realizes Greymoor has taken an interest in her.And it isn't choosing her.It's testing her.Drawn by instinct and circumstance, Lena enters the Iridian Apothecary.There she meets Vale Iridian, a man whose quiet gaze carries the weight of uncounted destinies. Iridian reveals a truth that bends the world around her: the city has a hidden architecture made of intent, cost, and consequence. Every life is a thread. Every decision creates imbalance. And someone must keep that balance from collapsing.Someone Greymoor can shape.Someone who cannot refuse forever.When Lena saves a woman fated to die, the city trembles. A broken timeline follows her, seeking acknowledgment-demanding resolution. From that rupture emerges Ember, a child who should never have existed, a new life born from Lena's refusal to accept a predetermined outcome.As the city awakens around her, revealing hidden corridors, shifting rooftops, and signs carved into stone, Lena learns that the Iridian Apothecary isn't a place. It's a role.A necessity.A responsibility the city extends only to those who can bear its cost.Iridian's time is ending.The city is choosing a successor.And Lena must decide whether to accept the burden Greymoor demands... or redefine it entirely.Through moving tunnels that shouldn't exist, rooftops that hum with purpose, and districts that behave like living organisms, Lena confronts the truth behind the city's balance: not all cities are built.Some are born.And Greymoor is alive.The closer she draws to the city's hidden core, the more the cures reveal their ultimate truth: the highest cost is never paid by the clients... but by the keeper himself.When the city asks for a final word-one that will shape its future-Lena understands that no role is inherited.It is claimed.The city wants balance.Lena chooses responsibility.And that choice rewrites Greymoor forever.The Thirteenth Prescription is a haunting, atmospheric urban paranormal thriller where streets breathe, fate bends, and every small act reshapes the fabric of a living city.A story about unseen forces, the weight of choices, and remedies that must be paid for-not administered.
