Hollow Victory (S03E08)

Challenger invents an innovative method to generate lift for the balloon, prompting the group to embark on a test flight. However, they soon encounter fierce turbulence, leading to a crash within the expansive caldera of a long-dormant volcano. Stranded in a perilous underground realm, their balloon sustains damage, leaving them with a dwindling supply of iron and only days to survive in the sweltering conditions. Aleece, a determined warrior-in-training, leaps into action to save them. She proposes to gather the necessary iron in exchange for a trip on the balloon. Accompanied by Malone, she devises a risky plan to steal from the vengeful exile, Arjax. When they are apprehended, Aleece and Malone must guide Arjax back to the balloon to escape death.
