Metru-Nui was an island at the northern most point of the Un-bionicle universe. The Matoran were lazy and worked in secondary industries. They created lots of smoke through their factories and created Global Warming. Turaga Dume, the island's leader has been getting a lot of calls off Al Gore recently saying "Stop killing your island". These calls have reached a point where Dume is creating the island's matoran into a military force, so he can kill Al Gore and get him to stop bugging him! Vahki eventually got eaten in front of Dume by the Matoran Nui.
