Sebastian Swan, a brilliant Slytherin alumnus and scion of a prestigious alchemical dynasty, commands unparalleled wealth across the wizarding realm. After a decade-long absence, he assumes the role of professor at Hogwarts, driven by ambitions far grander than mere instruction. When Snape demands answers about his unexpected return, Sebastian's responses escalate from pledges to elevate Slytherin's standing, to restoring Hogwarts' former glory, before finally revealing his ultimate vision: reshaping wizardry itself. Yet beneath his grandiose declarations and playful evasion of Veritaserum lies a purpose that transcends house pride and institutional prestige—a transformation of the entire magical world awaits. A tale of ambition, alchemy, and the extraordinary lengths one wizard will traverse to leave his mark on a legendary school and its traditions.
