Ga-Metru was the spiritual and educational center of Metru Nui, home to the Great Temple and the Fountains of Wisdom. It was the site of numerous protodermis canals as well as temples and schools. According to legend, it was the second region of the city ever built and was the one most favored by Mata Nui. Protodermis was pumped from the sea into Ga-Metru, where the purification process took place.1


Toa Nokama served Ga-Metru, where protodermis was researched and purified. Her hydro blades let her swim at high speed through the protodermis canals of the metru.2

Ga-Metru was traditionally the most peaceful section of Metru Nui, home to scholars and scientists. Often the only sound that could be heard was the rush of the protodermis falls.3

The protodermis fountains had ancient carvings.3

One could walk along the canals past the beautiful temples of Ga-Metru.3

In one part, a protodermis canal split off into a narrow feeder branch that fed protodermis into a central reservoir far below. The reservoir was a huge, circular chamber, lit by lightstones embedded in the ceiling.3

Ga-Metru was dotted by many ornate domes. Vhisola's classes were held in one of these domes. Vhisola's lab employed a male (non-Ga-Matoran) lab worker.3

Ga-Metru contained smaller temples as well, within view of the Great Temple.3

Ga-Metru was a huge academic center, with laboratories and schools where the Ga-Metru Matoran taught others and monitored the health of the city. It had dwellings for teachers and students.4

Students, like Vhisola, often had small indoor protodermis purification systems in their homes to use for homework assignments.4

Ga-Metru contained a number of mini-dams. Here tides of protodermis were held back so as not to overflow the metru's canal system. Each dam fed into a spillway, a wide stone channel through which liquid protodermis flowed into the canals as needed. The dam could be opened or closed using a main valve, which was controlled with a large wheel.5

Two Ga-Matoran in a fishing skiff encountered the two-headed Tarakava before it was brought to the Archives.5

Ga-Metru was known for its peace and tranquility. It was the spiritual and educational center of Metru Nui. Temples and schools lined the beautiful protodermis canals which ran through the district. Ga-Matoran so loved the atmosphere here that they rarely left the metru unless they needed to, and then their travels normally took them to the relative quiet of the Onu-Metru Archives. Traveling the streets of Ga-Metru or standing on the shore of the silver sea was an unforgettable experience. Some would even say that one could almost hear the voices of the Great Beings there. Legend had it that Ga-Metru was the second metru constructed after Ta-Metru and was the one most favored by Mata Nui.6

Ga-Metru was evenly divided between teachers and students. The pursuit of learning was so valued that the metru employed Matoran from other districts to take care of many jobs. This freed the Ga-Matoran to focus on their roles as teachers or students. Ga-Metru schools taught the history of Metru Nui, ancient Matoran dialects, and the science of protodermis, among other things. Students spent time in classrooms and labs, but they also took trips to see interesting carvings or new exhibits in the Archives. The very best students got to work in the Great Temple as protodermis purifiers.7

Ga-Metru also contained lesser temples and protodermis labs.8

Some parts of Ga-Metru were utterly silent, like Ko-Metru.9

Because the Le-Matoran hated the sea, all watercraft in Metru Nui, unlike other vehicles, were made in Ga-Metru, rather than Le-Metru.10

The public, upper levels of the Archives were frequently visited by groups of students from Ga-Metru.11

Ga-Metru contained the Fountains of Wisdom and the Protodermis Falls.12

In some areas of Ga-Metru, residents grew accustomed to, and in some cases even enjoyed, the melodic cry of dermis turtles at night.13

One of the most feared and hated kinds of Rahi in Ga-Metru was the doom viper.14

Matoran fishing boats operated in the sea off Ga-Metru.15

Tarakava haunted the shallow water around Ga-Metru and were a long-time menace to Matoran navigation.16

Ga-Metru boasted many schools. Among the subjects taught here were protodermis purification, translation, and Matoran history. Ga-Metru employed Matoran from other districts to do menial tasks so that Ga-Matoran could focus on their studies.17

Ga-Metru had broad avenues that led past temples, schools, and canals. Ga-Metru was Toa Nidhiki's least favorite metru, because it felt so clean and orderly. To him it felt as if a splash of water on the street would be cause for alarm.18

Ga-Metru was home to scholars and teachers. It was best known as the site of the Great Temple.19

Ga-Metru was the spiritual and educational center of Metru Nui. It was home to the Great Temple and many schools. It was a peaceful and beautiful place, known for its canals and fountains. Much of the daily work done in the metru was done by members of other tribes so that Ga-Matoran could be free to study.20

The liquid protodermis that flowed through the canals of Ga-Metru was purified, so it looked more like normal water than silver.21

Ga-Metru was full of teachers and students, and those who were particularly skilled were able to be part of the protodermis purification process.22

Ga-Metru had a location that Matoran had to travel to once a year to recharge their energy.23

A central spot in Ga-Metru held a place where Matoran could absorb a year's worth of energy from one visit.24

There was not much plant life on Metru Nui, other than some hedges and shrubs in Ga-Metru.25
