About this adventure

THE HOOK — A royal decree bearing the king's seal has been stolen from the Hall of Records in Hanseong, the capital of the Joseon Dynasty. The decree contains a secret clause that could legitimize a rival claim to the throne, threatening to plunge the kingdom into civil war. Those who discover the theft have only three days before the document is to be read aloud at the Grand Court Assembly — after which, its contents become irrevocable law. THE SETTING — The year is 1468, during the reign of K

Prologue

The air hangs thick with the scent of pine and woodsmoke as night descends on Hanseong. A chill wind whispers through the eaves of the palace, carrying secrets and anxieties alike.

A royal decree, bearing the sacred Crimson Seal, has vanished from the Hall of Records. This is no mere theft. The stolen document contains a hidden clause, capable of igniting a powder keg of political rivalries and plunging Joseon into civil war. With each passing hour, the conspirators grow closer to their goal — and the kingdom edges closer to the brink.

Queen Consort Yun Sohui

Human · Courtier

The composed and watchful queen consort of King Sejo, whose gracious exterior conceals a formidable political mind — and worried bad things may succeed where her own quiet prayers could not.

King Sejo of Joseon — Yi Yu

Human · Sovereign

A brilliant and ruthless king who seized the throne from his own nephew and has ruled through iron will ever since, now aging and quietly haunted by the blood that bought his crown.

Jo Tae-hwan

Human · Scholar-Bureaucrat

A composed and courteous senior court official who conceals the architect of the conspiracy — a grieving father and husband whose family was erased by the king he now serves with a smile.

Prince Yi Gwi-seong

Human · Exile

A soft-spoken prince sheltering in the northern mountains whose genuine reluctance to claim the throne makes him either the conspiracy's most tragic pawn or its most dangerous weapon.
