Terra Prime and the Prime System

This all about Terra Prime and the Prime System.

Terra Prime
Terra Prime is a terrain planet similar to earth. The size is about 100 times that of planet earth and 80% of its surface is water. There is one large continuous continent across the entire planet, along with numerous islands spread around the planet.

Cities are divided into:
 * Terrain cities
 * Sub-terrain cities (underground, under terrain layers or inside mountain layers)
 * Sky cities
 * Water cities
 * Underwater cities
 * Orbital cities

The capital city is Prime City, a terrain city located on the equator. The city is the largest, most advanced and most cosmopolitan city across the entire planet. The city is enclosed by mountainous ranges, thus, providing as a natural terrain protection for the city.

Prime System
Prime System is a star system located in the midst of a giant nebula, usually civilisations with TT lower than 3 wouldn't be able to detect or navigate to the Prime System; thus, providing as a natural protection for the utopia.

Terra Prime is the main planet in the system, along with three other planets, a desert planet, an ice planet and a volcanic planet.
 * Terra Prime
 * 7 moons: Wahidis, Ithynius, Thylanius, Albanius, Humnius, Sydanius and Thabahanius.
 * Mars Prime, the desert planet 2 phase jumps away from Terra Prime
 * Pluto Prime, the ice planet 5 phase jumps away from Terra Prime
 * Venus Prime, the volcanic planet 7 phase jumps away from Terra Prime

There are also numerous astro-cities and battle-stars spread across Prime System.

Prime system doesn't have its own sun and Terra Prime is at the centre of the System; thus, Terra Prime acting as the primarily planet, as well as the star. Prime System is in fact a sub-star system of a larger star system with a blue sun, Sol Una, at its centre. There are no planets and only asteroids around Sol Una. Prime System is dependent on the Una Star System; and the main star system provides as an additional natural barrier and diversion for the Prime System.
