Po-Metru

Nearly 80,000 years before the death of Mata Nui, when the Matoran went to war with each other, the different Metru formed alliances. Eventually, the Brotherhood of Makuta intervened and ended the fighting, and the hostility between the Metru dissolved.

Po-Metru was the Stone District in Metru Nui. The carvings and statues on Metru Nui were carved in Po-Metru. The local Vahki were Zadakh. It was near the northern "tip" of Metru Nui, and was where the Vahki were built. After the Great Cataclysm Po-Metruwas the least damaged part of the city, leading to its use as a shelter for Matoran while Metru Nui was being repaired. Turaga Vakama called Po-Metru the heart of "The great spirit of civilization." It was less organized than all the other Metru, with little camps of carvers dotted all around the land.

However, during the Great Cataclysm, Ta-Metru was destroyed along with the Vahki and the rest of the city. Ta-Metru was soon covered in webs and made into the home of the Roporak after the Visoraks' conquest of the city. Ta-Metru with the other parts of Metru Nui, were repaired 1,001 years later by the Staff of Artakha and was reinhabitated by it's former residents. Once Spherus Magna was reformed Metru Nui was again abandoned.
