The Swamp of Secrets
Battles continue to rage in Karda Nui, the core of the universe. While half the Toa Nuva and their Matoran friends defend the skies from bat-like Makuta, the other three heroes – Toa Tahu, Toa Gali, and Toa Onua – plunge to the swamp far below in search of the Mask of Life. Unknown to the three, the Mask of Life has created a body for itself and joined the fight above as Toa Ignika.
But they’re not alone. Three more Makuta, mutated by toxic swamp waters, ambush the three heroes as they search the dense, murky undergrowth. Even though the Toa Nuva are armed with new Nynrah Ghost blasters, these insect-like Makuta – Krika, Bitil, and Gorast – battle the Toa for possession of keystones. These stones are the means to unlock the secrets of awakening the Great Spirit Mata Nui.
Meanwhile, with the aid of Toa Ignika, Lewa, Pohatu, and Kopaka get the upper hand over their Makuta enemies, forcing them to retreat down to the swamp and their insectoid brothers.
Below, Tahu discovers a metal sphere embedded in a fallen stalactite, its smooth surface covered with concentric circle patterns. The object is surrounded by a protective shield, which the Toa Nuva can’t get through.
The remaining Toa Nuva, accompanied by a strangely altered Takanuva, Toa of Light, and the mysterious Toa Ignika, team up with their friends in the swamp. Confronted by eight powerful Makuta, the heroes must find a way to defeat their enemies and awaken Mata Nui. But even if they succeed, will their actions save this universe ... or spell its doom?
