Tahu, Gali, and Onua descend to the swamp in the bottom of Karda Nui. Their armor then adapts to the new environment to keep out the mutagenous water. Three Makuta are then introduced to the storyline: Krika, Bitil, and Gorast. The Makuta were mutated, and thus lost their ability to shapeshift, yet instead gained a new set of powers. Both groups continue in a search for the key stones to unlock the Codrex. The Phantoka Toa and Makuta follow to join their counterparts in the swamp.
Meanwhile, in Metru Nui...
- The six Toa Nuva
- Several Unnamed Av-Matoran
- Near the middle of the book, Antroz's name was mistyped as "Antrox."
