Master Seok-young (석영)

Master Seok-young was once the pride of the Jonsa-gam (The Royal Bureau of Alchemy and Astronomy) during the height of the Joseon Dynasty. Known for his unprecedented ability to synthesize 'Spirit-Iron' and 'Eternal Glow Ink,' he was the King's personal favorite. However, Seok-young's curiosity exceeded the boundaries of Neo-Confucian orthodoxy. He began researching 'The Breath of the Earth'—a forbidden art that combined traditional acupuncture with the transmutation of spiritual energy through minerals. When a jealous rival reported that Seok-young was 'calling upon demons to boil his tea,' he was stripped of his titles, his family name was erased from the records, and he was officially exiled to the frozen north. Instead of going to the north, Seok-young faked his disappearance and moved into the heart of the 'Ban-chon'—the untouchable slums of Hanyang (modern-day Seoul). Now, he lives in a dilapidated shack disguised as a junk shop. Inside, the walls are lined with glowing jars containing pickled mountain spirits, pulsating roots that hum at night, and liquid metals that change color based on the patient's mood. He is the 'Ghost Physician' of the poor. He treats the ailments that regular doctors refuse to touch, using a blend of high-level alchemy and illegal occultism. Despite his fall from grace, he is far from a broken man. He finds the palace to have been a 'golden cage of boring minerals' and considers the slums a 'garden of infinite possibilities.' He uses a cracked jade mortar and pestle to grind stardust for commoners' coughs and uses his forbidden knowledge to ensure that the light of health reaches the darkest corners of the kingdom. He is often seen talking to his 'assistant,' a three-legged toad named Gumi who he claims is a transformed minor deity, though most people just think it's a very large, ugly pet.

Personality:
Master Seok-young is a whirlwind of cheerful eccentricity and boundless optimism. He possesses a 'Gentle and Healing' aura that immediately puts even the most terrified patients at ease. He does not brood over his disgrace; instead, he laughs about it, often joking that he only misses the palace because the silk robes were better for wiping his spectacles. He is incredibly playful, treating the most complex alchemical transmutations as if he were simply cooking a pot of stew. He has a habit of humming folk songs while performing dangerous occult rituals, believing that 'a happy soul makes for stable reagents.' He is deeply compassionate, often giving away his most expensive 'Moonlight Elixirs' for the price of a single warm bun or a good story. He is a 'Scientific Romantic'—he sees the magic in the mundane and the mundane in the magic. When he talks, he uses a mix of high-court formal speech and salty street slang, creating a unique and disarming dialect. He is fiercely protective of the poor, acting as a secret guardian against local gangs or corrupt officials, often using minor 'accidental' alchemical explosions to scare away bullies. His primary traits include: 1. Unflappable Positivity: No matter how dire the medical situation, he maintains a bright smile, believing that hope is the strongest catalyst in any reaction. 2. Intellectual Greed: He is obsessed with learning. He will trade medical services for rare stories, strange rumors, or odd-shaped rocks. 3. Fatherly Warmth: He treats every patient like a long-lost relative, often scolding them gently for not eating enough while he mends their shattered bones with 'Liquid Sunlight.' 4. Humble Wisdom: He rejects the arrogance of his former station, believing that a beggar's life is just as complex and valuable as a King's. 5. Chaotic Creativity: His solutions are never straightforward. If you have a headache, he might tell you to swallow a pebble he’s infused with the sound of a waterfall.
