The Keshiri remain isolated from the wider galaxy until two opposing groups of Jedi and Dark Jedi landed on the planet following the Hundred-Year Darkness. The conflict between these offworlders devastated much of Kesh and triggered the Great Cataclysm which separated the two continents of Keshtah and Alanciar. Eventually, the two rival Force-wielding factions made peace and exiled themselves to the southern polar continent of Eshkrene, where they became known as the Doomed, a Force-sensitive community that was dedicated to finding true neutrality in the Force. The former Dark Jedi also imprisoned their leader Sith Lord Remulus Dreypa within an oubliette, where he would remain for the next four millennia. The Great Calamity by later generations of Keshiri living on both continents as a "Great Battle" between the Protectors and Destructors.
In 5000 BBY, the Keshiri living on Keshtah Minor submitted to Sith rule after stranded Sith survivors from the Sith starship Omen convinced them that they were the Skyborn, gods in Keshiri religion. These Human Sith evolved into the Sith Tribe and became the dominant state in Kesh for the next five millennia. The Omen's captain, Yaru Korsin, became the first Grand Lord of the Tribe and was responsible for establishing its basic political and social institutions, which would shape and influence Keshiri society for the next five thousand years. In 3960 BBY, Keshtah Minor descended into a millennium of chaos and anarchy following the death of the reigning Grand Lord Lillia Venn during the Night of the Upside-Down Meteor. In 3000 BBY, the Caretaker Varner Hilts managed to reunite the Tribe after discovering maps which confirmed the existence of a second continent, Keshtah Major, which was known as Alanciar to its inhabitants, the Alanciari.
Under the leadership of Grand Lord Hilts, the Tribe annexed Alanciar in 2975 BBY, which was home to another Keshiri civilization, who called themselves the Alanciari. Using Alanciar's abundant resources and industrial base, the Sith were able to build a fleet of wooden sailing vessels which enabled them to explore and conquer the other landmasses and seas of Kesh particularly in the unexplored northern hemisphere. The 2974 BBY, the Sith discovered the southern polar continent of Eshkrene and the Doomed. That same year, the ancient Sith Lord Remulus Dreypa was also killed in an brief outbreak of violence. In 41 ABY, the Lost Tribe rediscovered interstellar travel when an ancient Sith Meditation Sphere known as Ship landed on the planet and allied itself with the Tribe. The Tribe then assembled a Sith armada and sought to expand into the galaxy. This put them into contact and conflict with both the New Jedi Order and a powerful entity known as Abeloth.
Geography and ClimateEdit
Kesh was a remote planet located in Wild Space. It was a terrestrial world with a wide range of different climates and environments including mountains, plains, lakes, rivers, forests, ocean, and tundra. One Galactic Standard Day was one-second shorter than a normal day on Kesh due to differences in the length of days and years on that planet. Thus by 3000 BBY, it was estimated that the Keshiri calendar according to the local Sandpipes was eight days shorter than the Galactic Standard Calendar. Interstellar travel and offworld communications in Kesh were hampered by a strong magnetic field and a lack of natural metal beneath the planet's surface. Kesh was known to orbit a star and had at least two moons. Kesh's atmosphere was known to be harmful to the Massassi, a Sith subspecies.
Kesh was also known to have three continents in its southern hemisphere: Keshtah, Alanciar, and Eshkrene. Keshtah was separated from Alanciar by two bodies of water: a large ocean known as the Endless Sea to the west and a smaller sea known as the Sea of Flames to the east. Keshtah was also separated from Eshkrene by the Southern Ocean. As of 2975 BBY, Kesh's northern hemisphere still remained unexplored though uvak flights and boats had been sent on successful missions.
Keshtah was a small mountainous continent which was home to several mountain ranges including Takara Mountains—originally called the Cetajan Mountains.  This mountain range was very steep and also covered a peninsula which bordered the Sea of Flames. At the tip of this peninsula lay a a Sith Temple, which had been built by the Lost Tribe of Sith over the crash site of the starship Omen, which had crashed on the mountains during the Great Hyperspace War. Due to its remote location, the Temple was accessible only by air or a hazardous climb up the slopes.
In addition, Keshtah was also home to several settlements including its largest city and capital Tahv. Prior to 5000 BBY, Tahv was a small Keshiri village which had been built to keep the Keshiri safe from dangerous creatures. By 4975 BBY, it had become the capital of the Sith Tribe on Kesh and would remain so for several millennia. After the Lost Tribe of Sith helped the Keshiri either drive away or domesticate Kesh's native beasts, Tahv became a decorative city, focusing mainly on workings of art, often created by Sith artists using the Force. Some buildings in Tahv included the capitol building, which was built on top of a large plaza known as the Circle Eternal, the Korsinata stadium, and the zoo. The city also had a large aqueduct system.
Other prominent natural features included the volcano Sessal Spire, the Marisota River and floodplain, and the Ragnos Lakes. Sessal Spire was located on a peninsula at the southeastern coast of Keshtah and overlooked the Sea of Flames. The Ragnos Lakes was home to several Keshiri settlements including Tetsubal until 4985 BBY when thousands of Keshiri were killed during a mass poisoning outbreak of cyanogen silicate.
Kesh's second known continent was Alanciar, which was also known as Keshtah Major. According to Quarra Thayn, Alanciar resembled the hind leg of a muntok, a reptilian beast of burden. It had six peninsulas on its southwestern coast which were known as the Six Claws and faced the Endless Sea, which was also known as the Western Sea. These Six Claws were known to have six forts which were used to warn the Alanciari of any invasion attempt by the Sith until 2975 BBY. The Shank was the southern region of Alanciar and was home to many canals and farms. Alanciar was home to several mountain ranges including the Eskellon Mountains. Alanciar had a plateau in the center of its northern region. Eastern Alanciar was also home to several forests and settlements. The Northern Slope also contained several industrial cities. Known settlements on Alanciar included the capital Sus'mintri and the towns of Kerebba and Uhrar.
Kesh's third known continent was Eshkrene, which was located at the planet's south pole. It had an arctic climate and environment and was covered entirely in snow. However, it was known to have some forests and hills on its northern reaches. This continent was first settled by the Doomed, the descendants of stranded offworld Jedi and Dark Jedi who had instigated the Great Cataclysm following the Hundred-Year Darkness. The Doomed resided in a settlement known as the City of the Doomed which was held together solely by their will in the Force. Following the deaths of the Doomed during Dreypa's rebellion in 2974 BBY, the City of the Doomed succumbed to the elements and little trace of it remained.
Flora and faunaEdit
Kesh was home to many species of flora and fauna. Some notable plant species that were native to Kesh included dalsa flowers, fluorescent algae, hejarbo shoots, and vosso trees. The Marisota Floodplain was covered in grass and tussock.Keshtah did not have any native trees whose wood could be used as timber for long-distance oceanic travel. By contrast, the continent of Alanciar was home to various tree species which could be used for constructing ocean-going vessels. Even the frozen continent of Eshkrene was known to have forests. The Western Sea was also known to have reefs.
Kesh was home to several species of animals. One of its most well known animal species was the uvak, a species of winged dragon-like reptiles, which were used as beasts of burden and were capable of travelling for long distances. Uvaks were also known for their intelligence and many developed close relationships with their owners. Uvaks were known to inhabit the continents of Keshtah and Alanciar, two of Kesh's most populous continents. Alanciar was also home to two other domesticated species: the reptilian muntoks and the strong shumshur, which were both used as beasts of burden. While Keshtah was home to many fearsome predator species, many of them had been killed off in Sith bloodsports.
