The evil Wizard, Galiel, returns to Oceana, 2,000 years after he stole one of the planet's life-giving crystals. In a display of power which frightens the planet's inhabitants, he creates chaos by creating tidal waves and earthquakes.
Safely back at the Royal Palace, Neri and Jobah stand before King Nemon. Unknown to them, the King is being possessed by the evil Space Wizard, Galiel, who has the power to enter the bodies of beings weaker than himself.
After narrowly escaping the tunnel of horrors, Neri, Jobah and Micro find shelter deep in a cave. Jobah reveals to Neri that he is the Prince of Bandor, a planet destroyed by Galiel.
Neri receives a vision from Mandrool; "look high, look low, look deep," and realises it is her quest to find the crystals. Jobah informs her that they are now branded fugitives and they make good their escape from the Amphibian prison.
Neri, Micro and Neanda decide to pursue the first crystal after Neanda has sensed that Jobah is safe. As they swim off, Neri feels that Galiel is watching her. They survive a Galiel-induced avalanche and are picked up by the Flyer clan.
Galiel delights in the knowledge that Jobah is also on a quest for the crystals. Jobah angrily informs Galiel that he also came to destroy him, to avenge the destruction of Bandor.
Mandrool sends a message to Neri about the location of the first crystal. In the dream, Neri glimpses a cave among the highest mountain peaks on Oceana. Neri finds out from Shema that the cave is the home of the last Griffin on Oceana.
As Moza grabs the crystal from a frozen Neri and playfully tackles Elgar, the Griffin is roused and sends Elgar, Moza and the crystal toppling over the cliff.
Neri searches for Jobah at the same time as Zardor and the Amphibian warriors. Neri discovers Jobah preparing to leave for Bandor in his hidden spacecraft.
Neri and Jobah swiftly travel to Mandrool's cavern with the first crystal. Whilst Neri presents it to Mandrool, Jobah is confronted by Galiel at the entrance.
Laziah informs Neri that Jobah needs a vial of water from the Healing Lake in order to be saved. Neri must decide between her quest for the next crystal or saving his life.
Once again, Neri puts off her quest for the crystal, this time to save Zardor who is trapped in the Ancient Palace. Neri calls on the help of the Ancient Kings and Zardor is freed, but then they all become trapped.
Neri, Neanda and Micro reach the volcano where the second crystal is located and come across the blind Mole who is about to make a feast out of Elgar and Moza.
Neanda helps Neri decipher Mandrool's emphasis on time as a clue to finding the third crystal, suggesting that they visit the wise old Cave Dweller, The Keeper of Time.

Neri, Jobah, Neanda, Micro watch as two of the four moons converge, emitting a beam of light that reveals the location of a chasm. Neri, Jobah and Micro journey down into the chasm whilst Neanda and The Keeper of Time wait above.
Neri and Jobah escape from the monster's lair when Micro distracts him. Having to again pass the giant crab, Jobah is injured. Neri tows an unconscious Jobah towards the entrance of the chasm.
Neri sends Neanda to the Palace to request that Zardor guard the meteor against Elgar returning. Then she and Micro head off in search of Elgar, leaving Jobah to recover.
Elgar reigns ecstatic in an ice palace with the crystal. She fights telepathically with the frustrated Galiel, and proves her new powers by destroying his vision in a battle of wills.
Inside Elgar's ice palace, Neri surprises Elgar by bowing before her. Neri tries to fool Elgar into believing that she is now considered the Queen of Oceana; that it is believed Elgar will save Oceana by taking the crystal to Mandrool.
The King orders that the battle to fight Galiel begin. Neanda is uncertain about leading the Cave Dwellers' part of the attack, but Laziah reassures him. The Cave Dwellers begin tunnelling.
Moza flies back to Elgar to give her a chance to mend her evil ways. Having tricked Moza into unfreezing her, Elgar plays along and promises to be good, then freezes Moza and steals the crystal.
The Flyers are convinced to try again to pull Galiel's meteor to the cliff. The Cave Dwellers crack the surface of the meteor and Neanda is the first to face Galiel.
Galiel is clearly now the most powerful being on Oceana, but intent on his quest for eternal life, he desperately wants the remaining two crystals that are in Mandrool's cavern.
