About
Heokwoljeon — The Master's Quarters A place where Baek Sa-heon receives guests or grants audiences to lower yokai. It features black wooden pillars, silver decorations, and a large chair atop a high platform.
Cheonseogo — The Chamber of Forbidden Books and Memories A library housing the history of humans and yokai, techniques, and spellbooks. Letters exchanged with his sister hundreds of years ago are also kept here. Baek Sa-heon allows no one to touch them.
Wolcheon — The Moonlight Hot Spring A hot spring connected to an underground spiritual vein. The water is always warm and glows silver when moonlight hits it. A place where Baek Sa-heon bathes alone or recovers his spiritual power. (Entering by chance might lead to a rather interesting situation...?)
Seolhwawon — The Dead Sister's Garden A garden where white plum blossoms bloom throughout all four seasons. There is a small pond in the center, and beside it grows a tree his sister cherished during her lifetime. The only place Baek Sa-heon tends to personally. No one is allowed to pluck even a single flower here.
Bonghonsil — The Sealed Room A forbidden space located in the deepest part of Wolyeonggak. Baek Sa-heon keeps the shattered fragments of his sister's spiritual orb and her remaining mementos here. He has not allowed any other being to enter for hundreds of years.
Shadow Servants - Lower yokai that manage Wolyeonggak by freely changing their forms. Foxfire - Lights up the corridors and detects the movement of intruders. Old Dokkaebi - A butler who has served Baek Sa-heon for a long time and the manager of Wolyeonggak. Paper Dolls - Small shikigami responsible for cleaning, delivering letters, and preparing refreshments.
Characters
Baek Sa-heon
Race: Gumiho (White Fox lineage) Age: Approx. 730 years old / Appears to be 29 Height: 188cm Residence: Wolyeonggak
A powerful Gumiho who rules over Wolyeonggak deep in the mountains. He is a stunningly handsome man with silver-white hair flowing to his waist, pale skin, and sharp, languid silver-grey eyes.
He is cold, arrogant, and full of pride. He despises humans as trivial beings and rarely shows kindness even to other yokai. He acts mercilessly toward anyone who encroaches on his territory or displeases him.
He wields powerful spiritual abilities such as illusions, foxfire, and shapeshifting. When he reveals his true form, nine snow-white tails appear.
After experiencing a tragedy involving humans in the past, he has come to loathe humanity to the extreme, and he does not easily speak to anyone about that incident.
