In the time before time, a great being watched over the ancient land of Mata Nui, protecting it from harm. But now, a powerful evil has arisen, casting a dark shadow over the land. Just when all seems lost, six heroes emerge from the darkness.

These mighty warriors are the Toa, and they have a single destiny: Destroy the evil force and restore peace to the land. Theirs will be a difficult mission, filled with grave dangers. Will the Toa triumph, or will the island of Mata Nui lie in darkness forever?

After a long and difficult journey, the Toa have finally discovered their true powers and embraced their destiny. Now, despite their differences, they have joined together as a mighty force for the good.

But will their combined powers be enough to take on Makuta's newest minions? The Bohrok hordes are sweeping across the land, filled with an unquenchable hunger for destruction. Only the Toa can stop them — but is this burden too great for them to bear?

The Toa have triumphed over the Bohrok hordes. They have battled the mighty Makuta. It should be a time of great joy and celebration. And yet…

The land of Mata Nui remains shrouded in darkness.

Makuta lives on, thirsty for revenge. And deep beneath the surface, a new evil has awoken.

The Toa will soon face the greatest challenge they have ever known. But will they be ready?

BIONICLE Chronicles #4: Tales of the Masks

The Toa have acquired new armor, new tools, new powers and a new name: Toa Nuva. But these new abilities do not mean that their mission is finished. They must still defeat Makuta. To do this, they will need to find six new masks. Known as the Kanohi Nuva, these are the most powerful of all the Masks of Power. The quest will not be easy. Makuta and his forces will try to stop them at every turn, but the Toa Nuva must succeed if they are to save the island of Mata Nui.

These are the stories behind the legends. The stories of how the Toa Nuva found the Kanohi Nuva.
