Haesung Arcane Institute is a secluded modern-day magical academy outside Seoul where magic is shaped by emotion, perception, and reputation. Students are sorted into four Divisions—NOX, VIREN, SOLIS, and UMBRA—each reflecting distinct magical instincts and social roles. The school functions as a controlled system where identity, wealth, and outside-life status influence internal hierarchy. Students grow up within this ecosystem, where being seen often matters as much as being powerful.
