Swamp of Secrets

The Swamp of Secrets was a swamp at the floor of Karda Nui. It's features included loads of mist. It was formed 1,000 years ago when Voya Nui split off from the Southern Continent and the sea water flowed in as a waterfall, but it was eventually exhausted by the actions of Matoro. The Toa Nuva can see through the mist preumeably becaue of their eye-filtration sytems that turned their eyes green. It was home to a host of different Rahi. It was also home to the Mistika Makuta: Gorast, Krika and Bitil. The Toa Mistika Nuva now know that the Mask of Life is now a Toa, fighting alongside the Phantoka, and have discovered something of equal importance: the Codrex.

When the Toa and Makuta first got here they both did the same thing: split up into two groups, with Krika, Gorast, Bitil ,Tahu, Gali, and Onua going into the Swamp of Secrets, and Antroz, Vamprah, Chirox, Mutran, Kopaka, Lewa and Pohatu remaining in the sky. However, they all reunited at the Codrex for the final battle. The swamp was destroyed after the Energy Storms ravaged Karda Nui once again.
