"It's all here..Every bit of it. When we got here... our masks... our creatures. Wait, that's me! This was all meant to be. But why? Of course! United but not One. Duty... Unity... and now Destiny."

- Gali

Plot
Ekimu and the Toa slowly make their way to the portal in the Region of Stone. Ekimu starts telling them the legend of himself and Makuta that explains why Makuta was so jealous of his brother and was hungry for power. The Toa are shocked to hear what happened and continue their journey. The Toa quickly catch up to Umarak and see that he has collected all the pieces from the forbidden mask that he'll use to bring Makuta back to Okoto. The Toa discuss how they have an element of surprise when suddenly Umarak comes behind them and attacks them. Umarak summons the elemental beasts come to hold off the Toa while he runs to the top of the mountain where the portal is. Pohatu gets super mad and uses an explosion of stone to defeat all the beasts. The Toa and Ekimu run after Umarak and try to stop him from reaching the top. They fail and Umarak continues climbing. Umarak reaches the top and places the broken mask fragments around the portal, but the Toa try to stop him. Umarak defeats the Toa, trapping them in shadows, but Ekimu comes and merges with Agil, emitting a massive light that defeats the shadow, weakens Umarak. Ekimu, having lost his enhanced armor, turns back to his normal self. Both he and Umarak are weakened, and Gali steals a fragment of the broken mask from Umarak. While she's on her way back to the Toa, the dark portal traps her, drags her soul to the Shadow Realm and Gali's body is dropped to the floor. The terrified Toa seek for the bright side and say that Gali is smart and that she will find a way out of there. At the Shadow Realm, Gali's soul is hiding from Makuta and his minions that are Skull Warriors and Villagers as they pass through a path to Makuta's throne. Makuta speaks of true power and stopping the Toa from having their powers as Gali secretly sneaks behind him and his minions into a secret room where the full prophecy is written on the wall. From the day they arrived, to finding their masks and creatures and to the exact moment when Gali got sucked in the Shadow Realm. Gali finds out what will happen after the battle and runs to the place where she got sucked in the first place so she can escape. Back at the black crater, Umarak is fully taken over by Makuta and used as the final fragment for the portal to be opened. Umarak gets sucked into the portal and Makuta begins to come out of it. The Toa are all shocked, but Ekimu says it is all part of the prophecy. Gali comes out of the realm and tells them that she knows how they can stop Makuta from entering their world. Tahu and the others question how she knows while she responds that she and Ekimu know. Ekimu then speaks how it was all foretold and that what happens now is their destiny. Gali uses her elemental power and strikes Makuta making him weak, telling the others that it is the final thing they would do. The other Toa join her and use their elemental powers. They recite "For Duty, For Unity, For Destiny!" while they weaken Makuta. Finally, Makuta is sent back to the Shadow Realm, and the Toa come back to the stars from where they came. The episode ends with Izotor finishing the Bionicle Legend to the rest of the Okotans and how they will summon the Toa back once they are needed. "This was the Legend of Bionicle," he finishes, saying that the Toa would return whenever the island needs heroes.
