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. How the Mistika could see through the mist may be revealed in summer this year. 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 do not yet know the Mask of Life is no longer in the swamp, but something of equal importance is: the Codrex.
