Ska Gora was a lush planet covered in forests, a location situated within the Tython system found in the Deep Core region of the galaxy. Over 36,000 years prior to the Battle of Yavin, settlers originating from the planet Tython, who were not Force-sensitive, established a colony on Ska Gora. The majority of the planet's inhabitants resided in city-ships that hovered above the surface of Ska Gora; however, a conflict erupted when the Wookiee warlord named Gharcanna brought members of his species to illegally settle on the planet's surface, resulting in the death of the illegal settlers and the destruction of large portions of the apex tree forests by fire.
Located at galactic grid coordinates L-10 within the Deep Core region of the galaxy, Ska Gora was a planet with a single moon orbiting within the Tython system. This planet, positioned as the eighth orbital body around its sun, named Tythos, was a temperate and lush world. Ska Gora's surface was largely covered by vast forests, swamps, and wetlands, and it was characterized by colossal apex trees. The atmosphere contained white clouds, and the planet also possessed at least one mountainous area. The vast majority of the planet's population, numbering at least in the tens of thousands, lived in city-ships that floated above the surface of Ska Gora, a measure designed to preserve the planet's natural wilderness. Strong winds frequently swept across the surface, stirring the jungles. By 25,793 BBY, many of the planet's trees had existed for thousands of years. The planet also contained deep mines from which valuable stones were extracted.
Ska Gora was colonized more than a millennium after the year 36,453 BBY by non–Force-sensitive settlers from Tython, which was the fifth planet in the Tython system, during their travels to neighboring worlds. In 25,800 BBY, Je'daii Daegen Lok had a Force vision depicting a dark army of warriors wielding blades of fire marching across a burning Ska Gora, with the city-ships crashing to the ground.
At some point between 25,797 BBY and 25,793 BBY, the Wookiee warlord Gharcanna illegally led members of his species to settle on Ska Gora's surface, in defiance of existing restrictions. The Je'daii Ranger Lanoree Brock was sent to Ska Gora by the Je'daii Council; there, she stayed with a Wookiee family and attempted to use diplomacy to persuade the Wookiees to leave the surface. However, Gharcanna refused to yield, and Brock was eventually compelled to attack the forests and kill the Wookiees present on the planet's surface. This action resulted in the destruction of large areas of the forests. These events, known as the Wookiee land wars, were deemed necessary to avert a civil war between the Wookiees and the other inhabitants of Ska Gora.
Ska Gora was initially shown in the Tython entry within The Holonet, a feature on the official website for Star Wars: The Old Republic, a massively multiplayer online roleplaying game from 2011 developed by BioWare. The planet was included in a schematic representation of the Tython system. The name of Ska Gora, as well as further details about it, were provided in Star Wars: Dawn of the Jedi 0, a preview issue of the Star Wars: Dawn of the Jedi comic books series. This issue, written by John Ostrander and drawn by Jan Duursema, was released on February 1, 2012.
