My Cleaner is the Archmage

At the Academy of Eseria, Caleb is no ordinary janitor. Beneath his humble cleaning duties lies a primordial archmage who wields the power of creation, though he has chosen to hide that strength behind the appearance of a lowly servant. His quiet disguise keeps him moving unnoticed through the halls of a school where status and magic decide everything. Caleb's secret is worth guarding, because the academy's elite would never expect the man sweeping their floors to hold such immense power.
