The Old Republic
“An incandescent organ of life, visibly vibrating with the pulses of billions.”
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 are (0,0,0) which effectively makes it the center of the galaxy. These coordinates also inspired the planet’s military designation, “triple zero,” though the actual galactic center is located in the Deep Core. As the de facto center of the galaxy, however, Coruscant is generally agreed to be the most important planet throughout most of galactic history, as well as being one of the wealthiest due to its advantageous location.
Geologically, the planet is composed of a molten core with a rocky mantle and a silicate rock crust. At its poles are huge ice caps that were popular spots for tourists. The entire surface of Coruscant is covered by a sprawling kilometers-high ecumenopolis and boasts a population of over a hundred billion. The statistic does not include transients, temporary workers, unregistered populace nor residents of orbital facilities. Because of these omissions, the actual population of Coruscant is estimated to be three times the official record.
Coruscanti skyscrapers dwarf all the original natural features, including mountains, as well as floors of oceans which once covered a large portion of Coruscant’s surface. Areas of Galactic City are broken up into 5,127 levels which are then divided into megablocks, blocks, and subblocks. Coruscant itself is divided into quadrants, which are divided into zones. Below the skyscrapers are Coruscant’s undercity, where sunlight never reaches. Artificial lighting illuminates these lower levels and advertisement holograms can be seen everywhere. There are numerous establishments for entertainment, catering to a myriad of alien species. The residents are collectively referred to as Twilighters.
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 is the artificial Western Sea, with many artificially-created islands floating on it, used by tourists on holidays.
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 melt ice and distribute water throughout the planet-wide city through a complex series of pipes.
Galactic City is divided into quadrants, several thousand in number, with each quadrant further split into sectors. Each sector is numbered on official maps, but sectors often have nicknames, such as Sah’c Town, also known as sector H-46, named for a prominent family that owns a large portion of its land, or The Works, the largest of Coruscant’s designated industrial zones.
The Works was once one of the galaxy’s major manufacturing areas, where starship parts, droids, and building materials were heavily produced for centuries, but as construction and industry became cheaper and more efficient and cheaper off-world, The Works fell into disrepair. The area gained a reputation as a hub of criminal activity and locals generally stay away from it.
A similar, but more dangerous area, was the Factory District, which was once the industrial heart of Coruscant until it too lost out to competition from producers in other Core Worlds. By the time of the Great Jedi Purge it lay in ruins and was almost completely deserted of sentients, because of the feral droids that prowled its streets. It was located on the opposite side of the planet, and was much more dangerous than the Southern Underground, Invisible Sector, which are infamous in their own right.
Another area of Coruscant is CoCo Town, an abbreviation of “collective commerce.” Many diverse species live there and work in manufacturing. A partially enclosed open-air plaza near the Senate building, the Column Commons, is so-called because it houses most of the HoloNet and news media corporations.
A series of orbital mirrors were set up that reflected the sun’s warmth and light. Combined with in-atmosphere systems, the weather on Coruscant is mild and temperate. The lower sections of the city are warmer and tend to be more humid.
The planet produces trillions of tons of waste every hour. Though almost everything on the planet, from clothes to packaging and machinery is recyclable, some waste is too dangerous to recycle. Such items included worn-out hyperdrive cores which are delivered to one of the planet’s five thousand garbage pits, where they are put into canisters and fired into a tight orbit around the planet. Garbage ships then collect them and transport them to nearby moons for storage. Some of the more dangerous materials are shot into the nearby sun for complete incineration. Garbage not exported or destroyed is mixed into a slurry of silicone oils and processed by garbage worms which chew it into pellets while removing any remaining organics, plastic, or recoverable metals. They turn millions of tons of pellets into carbon dioxide, methane, and other gases.
Coruscant enormous population and industrialization also produces massive amounts of carbon dioxide and heat energy. Thousands of carbon dioxide-reactive atmospheric dampeners were put into place in the upper atmosphere to prevent atmospheric degeneration. The first set of these planet-wide dampeners, developed by the Galactic Republic, was known as the Coruscant Atmospheric Reclamation Project.
Near the planet’s core are a number of massive power relay stations. The lowest levels were abandoned to mutants and scavengers, such as the cannibalistic, mythical Cthon. The foundations of many of the buildings, some of which weigh billions of tons, also extended deep into the planet’s crust.
Galactic Standard Time was developed on Coruscant and so is tied to the daily and yearly cycle of the planet. A Standard day, like Coruscant, is made up of 24 hours, while a Standard year’s 368 days reflects the length of Coruscant’s year.
