After awakening Ekimu and helping him recover the mask of Creation, the Toa believe they are ready to face Makuta...but the time has not yet come. Each Toa is aligned with one of the island's six elements, but to master those elements they will have to find the masks of Unity...and tame the elemental creatures that protect the masks. Only by completing this quest will the Toa become strong enough to ultimately face Makuta. But a powerful new villain is operating on Makuta's behalf. Umarak, the Hunter, is a fearsome creature who moves through the shadows that surround us. Now, as his Shadow Traps track the Toa, Umarak follows, knowing that control of the elemental creatures is going to be pivotal in the challenges that lie ahead. The Toa find their creatures...and while some make friends with the creatures immediately, others mistake the creature's protective nature for aggression. But the battles end end with the Toa realizing that in the realization that real unity comes from not from conflict but from cooperation and now not conflict. When the Toa mingle their elemental powers with those of the creatures, the Toa unlock a whole new level in themselves... The Toa come away from the experience with powerful new masks and powerful new allies.
