My Farmer Dad Is Secretly an ArchmageEpisode 2

Eden Thorne—the most powerful mage ever, the legendary Oracle Mentor—has disguised himself as a lowly peasant for twenty years since defeating the dark forces. Even his son Garrett, who fought his way to become Knight Paramount, remains unaware of his father's true identity. Now, with the Dark Lord's return, the Oracle emerges once again to protect the kingdom of Vern—only to be mistaken for a mere beggar by the capital's nobles. These snobs are about to learn: Eden is their only savior.
