"Even advanced species like the Chiss had found a way to make icy planets into homes."
―An artist, in his journal[src]

Csilla was a frigid, ice-locked planet in the Unknown Regions. It was the homeworld of the sentient Chiss species and a part of the Chiss Ascendancy. Though largely unknown to the wider galaxy during the age of the Galactic Empire, exploratory missions to the Unknown Regions conducted years later revealed Csilla and other worlds that could be reached through cautious hyperspace jumps.

Description[edit | edit source]

Csilla was a cold, ice-locked planet[3] located in the Csilla system[2] of the Unknown Regions, at the coordinates F-8[1] on the Standard Galactic Grid.[6] Its capital was the city of Csaplar, which was located underground.[2]

History[edit | edit source]

Csilla was inhabited by the Chiss for thousands of years. Approximately 1000 years before the Clone Wars, however, its star began to dim, causing the planet's surface to freeze over. Because of the change in temperature, a majority of the planet's four billion residents moved offworld to the planets Rentor, Avidich and Sarvchi. Those who remained moved underground. Chiss space was generally considered safe from outside local threats, though Csilla was openly attacked[2] in 19 BBY.[7]

The attack on Csilla occurred on 19 BBY. Three unknown enemy capital ships emerged from hyperspace and attacked the orbital defense platforms. The defenders, although shocked momentarily, began firing within a minute and soon destroyed all three of the ships and all wreckage as to not damage the planet. All leadership on the planet went to underground bunkers and stayed there for several hours to see if there were any follow up attacks.

The Chiss and their home planet were largely unknown in other regions of the galaxy. Consequently, when an Imperial scouting party led by Captain Voss Parck encountered Thrawn[8] sometime between 13 BBY and 11 BBY,[9] Parck instructed cadet Eli Vanto to learn anything he could from the alien about his species and homeworld.[8]

Sometime after the Battle of Crait[10] in 34 ABY,[11] the pirate Hondo Ohnaka included Csilla in the galactic map of his book named the Galactic Explorer's Guide.[10] Although dangerous hyperspace anomalies limited exploration of the Unknown Regions, the occasional exploratory missions of the region conducted[12] by 35 ABY[13] revealed some navigable worlds—including Csilla, Ilum, and Rakata Prime—that could be reached through careful hyperspace jumps.[12]

Inhabitants[edit | edit source]

A part of the Chiss Ascendancy,[5] Csilla was the homeworld of the sentient Chiss species.[4]

At some point, an artist traveled around the galaxy and wrote about the Chiss and their ability to settle into icy planets in his journal. The document was later restored and published by the Graf Archive[4] sometime after 34 ABY[14] and included a mention of Csilla as the Chiss homeworld.[4]

Behind the scenes[edit | edit source]

Csilla was first mentioned in the new Star Wars canon on a map featured in the 2016 article Where in the Galaxy Are the Worlds of Star Wars: The Force Awakens?,[15] before making its first appearance in Timothy Zahn's 2020 novel, Thrawn Ascendancy: Chaos Rising, the first installment in Star Wars: The Ascendancy Trilogy.[2]

  7. The Del Rey Star Wars timeline places Thrawn Ascendancy: Chaos Rising after Dark Disciple and before Star Wars: Episode III Revenge of the Sith. Furthermore, Star Wars: The Clone Wars Chronological Episode Order on (backup link) places Dark Disciple between "A Death on Utapau" and Star Wars: Episode III Revenge of the Sith, which are dated to 19 BBY by Star Wars: Galactic Atlas. Since the events of Thrawn Ascendancy: Chaos Rising are set between the events of Dark Disciple and Star Wars: Episode III Revenge of the Sith, they must also occur in that year.
  8. 8.0 8.1 Thrawn
  9. The Del Rey Star Wars Timeline (backup link) places Thrawn between Solo: A Star Wars Story and A New Dawn. Solo: A Star Wars Story The Official Guide establishes that the prologue of Solo takes place six years after the formation of the Galactic Empire, which Star Wars: Galactic Atlas dates to 19 BBY, thus placing the prologue of Solo in 13 BBY. Star Wars Rebels: The Visual Guide dates Kanan Jarrus and Hera Syndulla's first meeting, which is depicted in A New Dawn, to six years before the events of the Star Wars Rebels animated series, which begins in 5 BBY, according to Galactic Atlas, thus placing the events of A New Dawn in 11 BBY. Therefore, the Empire's first encounter with Mitth'raw'nuruodo, as depicted in Thrawn, must have occurred sometime between 13 BBY and 11 BBY.

  12. 12.0 12.1 Star Wars: The Rise of Skywalker: The Visual Dictionary
  13. According to Star Wars: The Rise of Skywalker: The Visual Dictionary, the events of Star Wars: Episode IX The Rise of Skywalker take place one year after the Starkiller Incident. Since Star Wars: Galactic Atlas dates the Incident to 34 ABY, The Rise of Skywalker must take place in 35 ABY, while all exploratory missions into the Unknown Regions prior to that event likewise happened by 35 ABY.
  14. Star Wars: Alien Archive establishes that the restored in-universe journal discusses Poe Dameron's mutiny against Amilyn Holdo, which is depicted in Star Wars: Episode VIII The Last Jedi. Since the events of The Last Jedi take place after the events of Star Wars: Episode VII The Force Awakens, which Star Wars: Galactic Atlas dates 34 ABY, the document must have been published after that year.
