Coruscant is a planet located in the Core Worlds. Located at the intersection of numerous major hyperlanes, including the Perlemian Trade Route, the Corellian Run, the Metellos Trade Route, the Koros Trunk Line, and the Leisure Corridor, its hyperspace coordinates were (0,0,0) which effectively made it the center of the galaxy. though the actual galactic center was located in the Deep Core.
Geologically, the planet was composed of a molten core with a rocky mantle and a silicate rock crust. At its poles were huge ice caps that were popular spots for tourists. The entire surface of Coruscant was covered by sprawling kilometers-high ecumenopolis, and boasted a population of over a hundred billion to several trillion, depending on the era.
Coruscant was once a world mostly covered in oceans.
However, all natural bodies of water were drained and stored in vast caverns beneath the city as a result of years of overpopulation. The only body of water visible was the artificial Western Sea.
With no other bodies of water available to feed and water its trillion inhabitants, Coruscant's architects, along with many others from around the galaxy, worked together to build a self-contained eco-system in the massive buildings set all over the planet. Polar cap stations also melted ice and distributed water throughout the planet-wide city through a complex series of pipes.
Around 200,000 BBY,the planet Notron was home to two species: the grey-skinned Taung and the Zhell, the ancestors of the modern Humans.
The Thirteen Nations of Zhell eventually came into conflict with the Taung, and the Battalions of Zhell fought the Taung in a fierce war. However, during a battle at the city of Zhell, a volcano erupted, and the Taung overran the terrified Zhell in the battle that followed.
Taking the victory and the cloud of volcanic ash as a sign of divine favor, the Taung adopted the name Dha Werda Verda (the Warriors of Shadow). However, they were ultimately driven off of Notron to the planet Roon by the Zhell.
The leaders of the Thirteen Nations are believed by archaeologists to have been buried near the planet's south pole, in the structure that became known as the Ice Crypts.
Sometime around 100,000 BBY, the Columi species visited Notron—known by that time as Coruscant—though they dismissed the world as primitive and a disappointment.
Coruscant's Human natives began to urbanize their homeworld after the departure of the Taung,
and archaeologists later believed that the historic Petrax Historic Quarter was the site of the planet's first skyscrapers.
The Gree species also had contact with early Humans, building Coruscant's original infrastructure, and by the approximate date of 90,000 BBY, the ecumenopolis later known as Galactic City had begun to build upwards.
As the Human population soared, they were forced to develop the first atmospheric scrubbers, delivery pipelines, recycling plants, and hydroponic farms, and instead of burying unrecyclable garbage, Coruscant's inhabitants built cannons that launched canisters of waste into orbit where garbage scows could tow them out of the star system.
Around 30,000 BBY, the Rakata species discovered Coruscant and incorporated it into their Infinite Empire. Some Humans were taken as slaves and put to work across the Empire, though the remaining Humans learned from their rulers' technology and developed sleeper ships. Over the next several centuries, the Coruscanti dispatched a number of sleeper ships, and by 27,500 BBY, their ships had established colonies on Metellos, Alsakan, Axum, Tepasi, Alderaan, Kuat, Rendili, Corfai, Corellia, and the worlds of the Ringali Shell region. Around 27,000 BBY, they launched ships even further, seeding the planets Barseg and Janilis VII in the distant Tion Cluster.
