Silver Sea

"The Vahki gathered at the newly made gap in the rail and looked down. [...] All that could be seen were the waves, beating against the bridge supports as if they hoped to bring them down."

- Narrator, Legends of Metru Nui

The Silver Sea is an ocean of impure Liquid Protodermis which encompasses most of the Matoran Universe.

History
Liquid Protodermis is drawn from the sea, purified, and sent to parts of the Island City of Metru Nui, mainly in Ga-Metru, where it is made into metal and used to create masks, disks, and other objects. During the Toa Metru's fight against Teridax, the Kanohi Vahi was knocked into the Silver Sea, and was later retrieved by Vakama. Due to its' extended exposure to the sea however, the Vahi had rusted orange. After finding a safe island paradise for the Matoran, the Toa Metru sailed back across the Silver Sea to Metru Nui on the Lhikan II before being mutated into Toa Hordika. Around the same time as the Great Rescue, "The Shadowed One" threw a Kanohi Kakama, which had belonged to a deceased Toa Mangai, into the Silver Sea. Sometime later, the Kanohi Kraahkan was tossed into the Silver Sea by the Piraka Reidak and was eventually retrieved by Makuta Icarax.

Landscape
The Silver Sea has a silver-like appearance, from which its' name is derived. During the Great Cataclysm, water from Aqua Magna diluted it slightly.
