Gem Homeworld/Locations

This is a list of known locations on the Gem Homeworld and other planets controlled by Gems.

Description
Homeworld appears to be split into two sections: an upper level and a lower level. The lower level (the surface of Homeworld) is barren and lifeless, likely because the Homeworld Kindergarten drained the life force out of the planet. The upper level is where modern day Homeworld cities and structures appear.

Unknown City
Homeworld is home to a highly advanced city. Skyscrapers can be seen with thin white tubes connecting them. Lights of different colors can be seen travelling through these tubes. There are also white pedestals with red inverted triangles on top. At the bottom of one of the skyscrapers are cell-like structures, very similar to the cells inside of the Gem Warship. There is a white flower-like mechanism in the city attached to an anvil and a circular black structure on top, bearing resemblance to the shape of a Roaming Eye ship. In the distance, green tubes can be seen connecting to triangular structures, and there are also black inverted pyramids which are identical to the Pyramid Temple on Earth. White Diamond's Ship can also be seen in the distance.

Known Locations

 * Docking Bay: There is a building near the city with a lime green interior. Gems enter the docking bay to park and exit ships.
 * Trial Building: While it is unknown if the trial building is in the same building as the docking bay, it is also located in this city. There is an empty pink room for the defendant to stay in until their trial, which connects to a trial room, where court cases take place. The exterior of the building is black and has the shape of a Roaming Eye.The Trial 250.png
 * Deep Cavern: Below the trial building is a large, gaping hole between several buildings which goes straight down to Homeworld's surface. The building walls have several designs; notable wall designs resemble cheese graters and holes which resemble the cells aboard the Gem Warship and those seen under the Ancient Sky Arena. White tubes with different colored beams flowing through connect each of the buildings.
 * Diamond Palaces: Shown in "Legs From Here to Homeworld", where the Diamonds live.
 * Diamond Ship Docking Bay: Shown in "Legs From Here to Homeworld", when Pink Diamond's Ship landed on Homeworld, it landed on the docking bay. The site consists of a raised square platform where Gems may assemble. At the corners of the platform are four additional platforms where ships may land which it has colored buildings and on top of the roof of the palaces.BC54A86D-FB6E-40FD-97AF-DDE81CAAD489.jpeg
 * Pink Diamond's Palace: The palace building is entirely pink which it's part of the Diamond Palaces where Pink Diamond's Ship is on the top of the roof. The interior is Pink Diamond's old room. It has a high ceiling and a hexagonal shape, with light pink glittering walls, a dark pink curtained window overlooking the Diamond Ship Docking Bay, and pink bubbles decorating the room. The diamond button to open the door to the tunnel with the moving pillars and has big seat, the table with little rocks, a vase, a destabilizer, a twizzler, a jewel, and two roses and the hologram picture. Then in "Together Alone", the old room now filled with his furnitures from his home on Earth what the Pebbles worked all night.
 * Yellow Diamond's Extraction Chamber: This room appears to be the Homeworld equivalent of a sauna. The building is entirely yellow, with two large statues crossing spears over the entrance, and the current Great Diamond Authority insignia on the door. The interior is full of steam, with large seating for the Diamonds, two large statues with waterfalls coming from their mouths, and the steam vent in the small center triangle of the current Great Diamond Authority symbol.Familiar_084.png
 * Blue Diamond's Pool Chamber: The building is entirely blue, with the statue walls and the original symbol on the top of the door and another on the door. The interior is full of water and a waterfall, the original Great Diamond Authority symbol in the center of the door frame and Gem Language written on either side of the door frame, and a walkway leading to the inner chamber. The pool itself is rectangular, and has three large steps with three large pipes running under them, in which large streams of water seem to flow. Each of the four corners of the pool is decorated with one of the four colors from the original Great Diamond Authority symbol. At the bottom of the pool is a drain stopper moldeled after the original Great Diamond Authority logo.Familiar_147.png
 * Diamond Throne Room: The throne room has four colored thrones positioned like the original Diamond Authority symbol where White, Yellow, Blue, and Pink Diamond sit.Screenshot_20190102-121918.jpg
 * Prison Tower: The tower is dark grayish.Screenshot_20190102-111550.jpg

Abandoned Area
At the bottom of the cavern is the abandoned surface area of Homeworld. Being partially underground, (due to above ground structures) the area receives little light and is very dark. The area is barren, covered in dirt and rock. Many green tubes connect the walls together closer to the ground. Pedestals protrude from the ground, and old statues of Gems and fusions can be seen scattered around. Some pedestals have text on them written in the Gem Language. There is another hole in the ground that leads to an abandoned Kindergarten facility.

Known Locations

 * Abandoned Kindergarten: Going through another hole in the ground leads to a dark cave. At the end of the cave is a humongous Kindergarten, with holes scattered everywhere that are seemingly endless. Going through a entryway in a wall leads to another part of the Kindergarten, where the Off Colors had lived for many years. This Kindergarten is completely underground.

Yellow Diamond's Unknown Base
Yellow Diamond's Unknown Base is a location seen in "Message Received", when Peridot contacts Yellow Diamond and Yellow Pearl through the communicator.

Not much is known about the base's location, aside from the fact that it appears to be near or inside of an asteroid field.

In "Message Received", Yellow Diamond is seen in the control room using holographic terminals to access information quickly. These terminals presumably possess the same functionality as the Moon Base terminals.

Only a white floating chair atop a stepped diamond-shaped altar can be seen from the inside, seemingly where Yellow Diamond works. There is a large glass wall made up of triangular panels separating the control room from the outside where several asteroids float in space both near and far.

Gem-Controlled Planets & Moons
Other various planets and moons which have been conquered by the Homeworld Gems are often shown in murals on various Gem structures. Only two have actually been named so far.

Upsilon 9
Emerald mentions that Lars and the Off Colors crashed her personal shuttle on the planet Upsilon 9.

Klavius 7
A planet located in Sector 4. The Sun Incinerator was docked on the planet Klavius 7 and was heavily guarded by sixty-seven elite Citrines, before being stolen by the Off Colors.

Unknown Planet
A planet located in Sector 7 which was colonized by Yellow Diamond a long time ago. The planet itself is now mostly hollowed out and completely devoid of life.

Jungle Moon
The moon which orbits the planet is still covered by a thick jungle and organic life. The Moon Base that was constructed on its surface is now abandoned and damaged by plant growth.

Yellow Diamond's Asteroid Mines
Yellow Diamond controls a number of asteroid mines, presumably guarded sites containing materials for Gem technology.

Sectors
It is revealed in the episode "Lars of the Stars" that different areas of space are referred to as "sectors" by Homeworld.
 * Sector 4 – The location of the planet Klavius 7 where the Sun Incinerator departed and jumped into hyperspace.
 * Sector 7 – The location of the unknown planet and its jungle moon where Stevonnie was stranded after their conflict with Emerald.
 * Three unknown sectors – Mentioned to have been passed through by the Off Colors.

Trivia

 * Klavius 7's name may be inspired by the Clavius crater, one of the largest crater formations on Earth's moon, which was named after 16th century Jesuit priest, mathematician, and astronomer Christopher Clavius. Clavius is also the name of a fictional lunar settlement in Arthur C. Clarke's Space Odyssey literary universe, located in the same crater formation.
