Ko-Metru

Ko-Metru was the home district of the Ko-Matoran on Metru Nui.

History
Ko-Metru was built by the Matoran according to the Great Beings' specifications during the construction of the Matoran Universe.

In 20,576 CMT, Kakamu and various other newly-created Matoran were teleported to a school in Ga-Metru to learn about life as Matoran on Metru Nui. In her introductory speech, Toa Helryx told the Matoran that if they had any questions about Metru Nui that their teachers could not answer, then they should visit the Knowledge Towers in Ko-Metru if it was the season where the Ko-Matoran could accommodate their visit.

In 100,080 CMT, Blackout took over the Matoran Universe, brainwashed its Matoran, and ordered them to dismantle all of its buildings and use the materials to build Darkmount. It is very likely that most or all of Ko-Metru was dismantled in this initiative and its Matoran population were brought aboard the city-ship.
