Ozma

Sam takes Maya to a hidden shelter constructed in the distant past, and filled with ancient technology. This shelter is the source of the ship’s technology, and the secret of Sam’s plans to hunt the sand whale.

As Gido escapes with Maya, Sam sets off in pursuit with Mimay in tow. But their bike is no match for the Theseus sand cruiser, and Gido escapes. To catch them, they’ll have to go back under the ground with the Bardanos.

The Bardanos finds itself in Ozma’s nest: a strange cave filled with fresh water and life. Bainas shoots Gido’s mask, and the face beneath it is that of Sam’s brother.

Ozma’s nature is revealed, and it’s time for Maya to make her choice: begin a new era with the life inside the zone, or allow humanity to remain in control of a dying planet.
