The Crimson Ossuary

A Macabre Mystery of Art, Obsession, and Murder

The Crimson Ossuary is a complete Tier 1 campaign for the 5th Edition of the world's greatest roleplaying game, designed to guide characters from level 1 to 5. What begins as a simple investigation into a back-alley crime will drag your adventurers into a conspiracy that reaches the highest echelons of Silverpine’s society. As you pull on the threads of the mystery, you will find yourselves targeted by the very killer you hunt. Framed for a crime you didn't commit and branded as fugitives, you must race against time to clear your names, forge alliances with the city's treacherous factions, and uncover the Sculptor's true identity.

The truth is more horrifying than you can imagine. The Sculptor’s ambition goes beyond mere murder to a twisted form of lichdom. Can you unravel the conspiracy and stop the artist before his final, bloody brushstroke?

A Campaign of Escalating Stakes

Your party will begin as simple bystanders to a strange robbery, but they'll soon find themselves embroiled in a sinister plot far beyond their station. From the bustling Grand Bazaar to the treacherous shadows of the Briar Wards, they will hunt a killer who murders not for coin, but for bones.

When the party gets too close, the killer retaliates, turning the city's laws against them. Imprisoned and discredited, the adventurers must clear their names from within a grim city gaol before they can bring the true villain to justice. Their journey will force them to deal with powerful groups like the ruthless Serpent's Lotus crime syndicate, the zealous Blades of Veneration, and the politically powerful House Noctharis.
