Matrux Nui

Matrux Nui is the largest city on Spherus Magna, housing the many beings on the planet. The City also has a huge rahi population and the Onu-Metru Archives from the Matoran Universe have been rebuilt here. This area's palace is located in Le-Matoran Domain. It is the capital city on Matus Nui.

History
Before the city was built, all the Matoran on Matus Nui lived in all the other cities, the capital being Shanis Nui. They lived in peace, untill the attack of the MAX Brotherhood of Makuta. Once the war had started, new Matoran and Agori created by Mata Nui (he recreated his Glatorian form, and the Ignika gave him a fortress and all his old powers) were crowding the planet, so the Matoran on Matus Nui decided to create a new city. Bigger, stronger, and safe from the war.

Once the plans were made, they started building. By the time they were done, the city was dubbed Arakus Nui. They lived in peace and prosperity untill the Brotherhood started attacking, and their new city fell. Afterward, it became a fortress and rest stop for their armies.

They didn't give up, though. this time, the Matoran and Agori this time worked together to build untill finally they had done it. They built a huge city with giant protosteel walls, a palace, and plenty of room for everyone. Soon it became well known to everyone, and became home to many refugees of the war. It was successfully intruded once, but the intruder was expelled from the city very quickly. Later, it too was captured by the MAX Brotherhood and used to manufactuer war supplies. Soon it was reclaimed by a Team of Toa.

Locations
In the city, many people live here, so they decided to give themselves their own land, which are considered cities as well. This system worked out great. Matoran, Agori, Toa, and Glatorian live in certain areas but are free to visit any other parts of the city. Smaller walls defend these parts.

Ta-Matrux
Some of the Ta-Matoran and Fire Agori live here. This part of the city houses Rannu, former leader of the fire tribe. The Main army is trained here, But the other cities train some backup armies. The main supply of Kanohi and helmets are made here and shipped all over the world. To have a Matrux Nui Kanohi or helmet was a badge of pride and respect. They also delivered these privately. They also got a small strip of land near the Royal Palace where they actually made the Masks and Kanohi.

Le-Matrux
Since the Le-Matoran were so playful and needed plenty of space to roam free, they got the most land. The Agori and Matoran worked to build towers to jump across. The old chute system was rebuild here, too. The chute's mail system works like this: the package is sent from an area, goes there, and is sent out to the proper city in another tube. The other chutes sent private packages. They also created a railroad powered by Toa of Air. They used their wind to push the train foward. The Royal Palace is also located here

Ko-Matrux
Ko-Matrux was where the most history was located. Their museum told the history of Spherus Magna, The Matoran Universe, and even this city. If you were looking for food, then go to one of Ko-Matrux's Many restaurants, They have gotten a reveiw and declared their food finest in the city.

Po-Matrux
Po-Matrux has been making quality items for sale since the city was built. Many come here for vehicles, weapons, and many other things. Many Kanohi and Helmets from Ta-Matrux are sent here. This area was also where the most bars were located.

Onu-Matrux
The Onu-Matoran lived here, but since their weren't any Agori of the Rock Tribe who weren't Skrall, They lived alone. The Archives were also rebuilt here with more stuff and Beings than ever. The new stasis tubes were reinforced, and so far nothing has escaped. The most biengs live here than anywhere else.

Ga-Matrux
Ga-Matoran and Water Agori were taught about mainly history, the Agori taught about the Matoran Universe and the Matoran were taught about Bara Magna. Other Matoran were also taught here. This city was also located near the ocean, with a beach and everything. Basically, it had water, and tons of it. Fishing was how they made agricultural profit. They also had a giant arena for tons of different competitions. It is the one of the two only Glatorian arenas in the entire city.

Refuge City
All the refugees from the war lived here. Anyone who either needed a place to go or an area to escape the war. They got all they needed: a place to live, food to eat, and a hospitle to heal the wounded. They had the second largest wall (the first being the outer wall), since they were refugees and needed somewhere to stay.

Upper/Middle/Lower Class CIties
These cities are where the visitors stay. Where they stay depends on social status. If they were rich, people lived in the upper class. If they were average or poor people, they lived in the lower class. Anywhere in between lived in the middle class.

Upper Class
Where all the rich Matoran and Agori lived. They got the best food and expensive homes. The mainly sold Masks their are mainly made by Ta-Matrux Matoran. Toa could also live here. The Turaga of the entire city eats here sometimes.

Middle Class
Above average Matoran and Agori lived here. The people here got a nice place to live, and good food. They also had homes in the unused land.

Lower Class
Where all the poor to average visitors lived. They too got nice homes and good food. The Trade Market is also closest to them than any other class city.

Lake Area
Like the name suggests, the lakes are located here. The underground refuge is located here in case of any Makuta attacks. All the future warriors are also in the refuge in a secret room.

War Refuge
The Toa Army is trained here. This area also provides a hospitle to heal the wounded, Training grounds for training, and rooms for the soldiers to stay. Matoran can visit any time.

Palace Grounds
The perimeter of the Royal Palace is located here. This area, as said before, is located in Le-Matrux, and the royal palace houses many guards, servants, domestic and visiting dignitaries, Royal Guards, The Generals of the land, the Royal Advisors, and Turaga Mizok, the ruler of Matrux Nui and the entire island.

Unused Land
Land in the city used by no one. The land also houses Middle Class visitors. The land also contains paths to a chute entrance, the Royal Palace, and the Trade Market.

Outer Wall
The outer wall of the city is the first line of defense in the city. It has plenty of watchtowers and weapons to make sure enemies won't get in. The walls can be opened with a switch so Matoran, Glatorian, Toa, and Agori can get in.

Trivia

 * Matrux means "Indestructible" in the Matoran Language, which is ironic, considering the fact the walls are made of protosteel
