In "The Genie Who Feared June," the Challengers of the Unknown face a magical mystery when a genie erupts from a bank during a routine outing with Jo. As the team tracks the creature to the sorcerer Malvolio, it’s June’s unexpected command of ancient magic—whispered with a single gesture—that sends the genie fleeing. With Malvolio’s dark schemes unraveling in a crumbling factory and a forgotten mine, the team must rely on June’s quiet courage and the power of the opals to break the spell before the genie’s curse claims them all.
