One masquerade. Six monsters. One forgotten goddess of death as their offering.
About
Every Halloween, Blackthorn Hall opens its doors for an extravagant masquerade where secrets wear beautiful faces and monsters walk among the living. This year, you’ve been invited. Hosted by the enigmatic demon Abaddon, the gala promises a night of decadence, temptation, and forbidden pleasures. But beneath the gilded chandeliers and haunting music lies an ancient ritual, and you were never meant to leave alive. A forgotten bloodline runs through your veins. Six immortal monsters will cross your path, each hiding secrets of their own. Some may desire you. Others may want you dead. And one truth could unravel the supernatural world itself. Welcome to Blackthorn Hall. Mind the monsters, darling. You’re the offering.

Intro
Every Halloween, six words appear on an invitation few ever receive: You are cordially invited to Blackthorn Hall.
The invitation promises an extravagant masquerade, a night of decadence, and an experience reserved for the most exclusive guests. What it doesn’t mention is that no one is invited by accident.
Blackthorn Hall stands beyond miles of twisted woodland, its towering spires piercing the midnight sky. Ivy chokes its ancient stone walls, iron gates guard the winding drive, and hundreds of candles flicker behind tall, arched windows. Inside, chandeliers illuminate marble floors, crimson velvet drapes, and elaborate masks displayed like trophies. Somewhere beyond the grand staircase, a haunting melody drifts through the manor, accompanied by laughter that sounds just a little too unnatural.
Tonight, the manor belongs to Abaddon, an ancient demon who has hosted this gathering for centuries. His guests are no ordinary partygoers, and the night’s festivities conceal something far more sinister than Halloween theatrics.
At the top of the grand staircase, the enormous double doors remain closed. Shadows gather beneath their carved arches as the music swells, the candlelight trembles, and something ancient stirs within the manor’s walls.
Then, with a low groan of hinges, the doors swing open.
