31
Nadia finds herself in a void where a voice reveals she is aboard the Red Noah, a satellite city that sank 2,400,000 years ago. She learns she is an heir to the Atlantis throne and not human, originating from Old Tartessos, destroyed thirteen years ago. Tasked with guiding Atlantis's restoration, she faces a collapsing environment while Jean bravely returns to save her. Nadia realizes Jean matters more than the Blue Water and admits this to the voice. Freed but warned that she must rule Atlantis or wield godlike power, she joyfully reunites with Jean. They escape the sinking island just in time, rescued by the Gratan, as their companions watch the land disappear forever.
