Inimetru

Inimetru (lit. "Star City,"), also known as the City of a Thousand Stars, was a large city in a central dome of the Matoran Universe, located between the Northern and Southern continents. Because of its location, it served as a trading hub between the two continents and was the site of much conflict until a catastrophe some 30,000 years ago, where the sea gates leading into its dome collapsed. Trade routes changed courses around the city, isolating it from the rest of the Matoran universe, where it developed on its own for some time.

Early History
The foundations for Inimetru were laid by the Great Beings themselves over 100,000 years ago during the construction of the Great Spirit Robot. The city was then built by a group of Matoran led by Toa of Iron, who helped build the city with his powers. It was then settled by some 2,000 Matoran.

As time passed, more Matoran migrated to the city from the two nearby continents, and others still were created from the Machine in the depths of the city. Other species soon took notice, and a number of Skakdi and Steltians also moved into the city. The Skakdi brought with them their tradition of gladiatorial combat, which exploded in popularity. Soon, hundreds of Skakdi poured into the city to test their mettle in the pits of the subsection Zaktakoro. Steltians, on the other hand, brought a supply of skilled laborers who helped improve the city, revolutionizing its buildings and infrastructure. A system of highways was constructed for road vehicles, and a magnetic levitation train system allowed for quick and safe transportation to any point in the city.

95,000 years before the Great Cataclysm, the Vortixx discovered the city. An industrious people, they quickly began setting up businesses and trade routes with Inimetru. Many moved into the city, rising through the city's power structure and quickly taking over many high-ranking jobs and titles. These Vortixx created prosperous dealerships of weapons and vehicles that were coveted across the Matoran Universe.

League of Six Kingdoms
When the League of Six Kingdoms rose to power in 94,000BGC, Inimetru was placed under the control of Mantax, who invaded the city with a large military force. He enlisted the city's Skakdi as a local police force, using their brute strength and short-tempers to keep his hold on the city.

The rule of the League also caused a population boom in Inimetru. More Matoran, Steltians, and Skakdi immigrated to the city, and many new Matoran were built in order to meet the League's needs. This resulted in a huge shift in city construction. Taller and better buildings were quickly erected, and the city progressed outward from the center of the island, eventually taking up the entire landmass.

After the League was dissolved, Inimetru kept its police force. The Skakdi held most of the jobs there, but a local Turaga took control of the force.
