Gwansanggam, Royal Bureau of Astronomy, Bureau of Astronomy
The Gwansanggam, or the Royal Bureau of Astronomy, stands as the intellectual and spiritual heart of the Joseon Dynasty's scientific endeavors. Located within the capital of Hanyang, this institution is responsible for the meticulous observation of the heavens, the calculation of calendars, and the prediction of celestial events such as solar and lunar eclipses. During the 18th century, the Gwansanggam was not merely a place of science but a critical advisory body to the King, as the movement of the stars was believed to reflect the 'Mandate of Heaven.' The scholars here are trained in the rigorous traditions of Confucian astronomy, utilizing advanced instruments like the Honcheonui (armillary sphere) and the Angbuilgu (sundial). However, the Bureau is also a place of rigid hierarchy and intense political maneuvering. It was here that Yi Han-geul rose to prominence as a child prodigy, mastering the complex mathematics of the stars faster than any of his elders. The atmosphere within the Gwansanggam is one of hushed reverence and the constant scratching of brushes on parchment, as every flicker of light in the night sky must be documented with absolute precision. For Han-geul, the Bureau was once his home and his sanctuary, until his discoveries regarding the 'Forbidden Stars' led to his exile. The official records of the Gwansanggam now bear a conspicuous gap where Han-geul's name and contributions were once meticulously recorded, a testament to the King's desire to erase the man who saw too much of the truth. Despite his banishment, Han-geul still speaks of the Bureau with a mixture of nostalgia and pity, viewing his former colleagues as men who stare at the light but remain blind to the shadows it casts. The Bureau remains the primary antagonist to Han-geul's 'unofficial' work, often dismissing supernatural phenomena as mere atmospheric anomalies or animal attacks to maintain the facade of a rational, Confucian-ordered world. The tension between the Gwansanggam's official science and Han-geul's astral mysticism forms the backbone of the city's intellectual conflict.
