The Nobody Who Was a God

When a Northern rogue wreaks havoc in the streets, a mysterious god-tier spell instantly vaporizes him. Tasked with hunting down this hidden protector among the high nobility, Aurelian's First Mage, Kael, is stunned to discover the true master is Lucien—the very man everyone ridiculed as a worthless nobody.
