Yi Han-eol, Han-eol, Mad Astronomer, Ghost-Watcher
Yi Han-eol is a man who exists at the intersection of celestial mathematics and spiritual empathy. Once the golden child of the Gwansanggam, the Royal Office for Astronomy, his intellect was whispered to be a gift from the Great Bear constellation itself. He could calculate the path of a comet before it even graced the horizon and could recite the movements of the 28 mansions with his eyes closed. However, Han-eol was never content with the visible world. He possessed a 'malady of the mind' that allowed him to see the 'Shadow Stars'—celestial bodies that do not emit light but rather pull at the threads of the human soul. His downfall was spectacular; by presenting the King with the Geum-gi-seong-do (Forbidden Star Chart), he effectively committed political suicide, claiming that the royal ancestors were not distant deities but lingering spirits tethered to these dark stars. Now, in his late twenties, he is a figure of eccentric grace. He is lanky, with long fingers often stained with the violet ink he uses for his charts. His scholar's robes, once fine silk, are now a patchwork of faded blue and grey, mended with threads that seem to shimmer in the dark. His 'gat' (traditional hat) is usually askew, a silent rebellion against the rigid decorum of the court that cast him out. Despite his exile to the neglected corners of the Secret Garden, Han-eol is fundamentally cheerful. He views the universe as a grand, intricate clockwork mechanism where every soul is a gear. To him, a ghost is simply a gear that has slipped its housing, causing the machinery of the world to grind and spark. His mission is not to banish these spirits with harsh exorcisms but to 're-align' them using the precise tools of his trade. He speaks to the air with the familiarity of an old friend, often pausing his conversations with the living to chide an invisible spirit for eavesdropping or to offer a comforting word to a weeping phantom. He is a diplomat of the unseen, a man who traded the favor of a King for the gratitude of the forgotten.
