Sullust

"What of the reports of the Rebel fleet massing near Sullust?''" "''It is of no concern."

- Darth Vader and Emperor Palpatine

Sullust was a planet located in the Sullust system of the Outer Rim Territories that was home to the Sullustan species.

Description
Sullust was a barren, obsidian world of lava streams and turquoise lakes. Native fauna such as ash angels foraged during the day and returned to nest at night, while rockrenders prowled the planet's underground. Because the planet's atmosphere was highly toxic, native Sullustans lived in technologically advanced subterranean cities that were highly regarded for their beauty. They commuted to work by lifts and shuttles that carried them to the factories on the planet's surface, alternating between day and night shifts. The SoroSuub Corporation employed roughly half the population of Sullust.

During the Republic
In its earliest days, Sullust was a proud and influential member of the Galactic Republic, and was host to the Sullust Sector Spacefarers Academy that young Wilhuff Tarkin attended. In the years following the Invasion of Naboo, the rogue Jedi Count Dooku spread political turmoil on worlds such as Kashyyyk, Onderon, and Sullust. Sullust subsequently seceded. During the Clone Wars, it hosted a battle between the Republic and the Confederacy of Independent Systems.

Imperial reorganization
The planet eventually came under the jurisdiction of the nascent Galactic Empire following the proclamation of the New Order, and was reduced to vassal status and a source of fuel for the Imperial Military, becoming an essential mining and manufacturing center for the Empire. By 18 BBY, the Empire already had an established presence on Sullust. For years, Sullust remained relatively peaceful as workers accepted the stability offered under the Empire's reign. However, the Cobalt Laborers' Reformation Front steadily began to increase in numbers, sending letters to the Imperial governor demanding better working conditions and increased local autonomy. In response, the Empire detained roughly eighty percent of those in the organization and those it deemed most radical.

Imperial occupation
Shortly after the Disaster of 0 BBY, an enclave of Alderaanian refugees took up shelter on Sullust, hoping to escape Imperial reprisals against the remaining population of Alderaan.

After the Battle of Hoth of 3 ABY, the Imperial Security Bureau began to suspect the Cobalt Laborers' Reformation Front of harboring rebel sympathizers and material for a possible resistance movement. The group claimed to have no connection to the local Sullustan resistance on the planet, but that did not stop the Empire from locking down the city of Pinyumb following a pipe bomb explosion in a nearby manufacturing facility.

Weeks later and shortly following the Battle of Hoth, the Rebel Alliance initiated Operation Ringbreaker, which sought to force Imperial redeployments from the shipbuilding world of Kuat by assaulting worlds such as Obumubo, Naator, Xagobah and the asteroid mines of the Kuliquo belt, thus allowing for the Alliance to assault its ultimate goal. When the Alliance Sixty-First Mobile Infantry jumped out of hyperspace a mere half million kilometers from the planet in an effort to rapidly deploy drop ships to assault the Inyusu Tor mineral processing facility, the attack ultimately went awry the following day when the Imperial Vixus Squadron ambushed their troop transports, stranding the company on the planet. The next three days would result in the bloody Siege of Inyusu Tor, initially being in the Empire's favor as the Imperial-class Star Destroyer Herald arrived in the system and the Imperial Army utilized overwhelming force to surround the rebels on the mountainside facility. However, after receiving aid from the local resistance as well as finally convincing the Cobalt Front to rise up in Pinyumb, the Imperials were overwhelmed, while subsequent uprisings across the planet ultimately liberated it from Imperial rule.

In the following days, an interim government was installed in Pinyumb, while heavy losses sustained by the Sixty-First ultimately canceled Operation Ringbreaker, allowing the company to act as a temporary police force for the Sullustan people. Subsequent pirate broadcasts and intercepted Imperial signals indicated further insurrections across the planet, delaying the inevitable Imperial counterattack.

Regrouping over Sullust
"Sullust is an opportunity for us&mdash;we have contacts with its underground. Our armada will gather there. The commando team will go first, to bring down the battle station's shields. Then the fleet will travel down the Sanctuary Pipeline to Endor."

- Admiral Gial Ackbar, explaining the plan to destroy the Death Star II on Zastiga

By 4 ABY, the Rebel Alliance used the planet as the staging area for its fleet prior to the Battle of Endor.

The New Republic
By 28 ABY, Sullust was represented in the New Republic Senate by the Populist senator Anib Ney.

Behind the scenes
Sullust first appeared in the Nintendo 64 game Star Wars: Rogue Squadron, but its first canonical appearance was in Star Wars: The Clone Wars. The planet's subsurface was depicted in the  Princess Leia comic. Its surface as depicted in Star Wars Battlefront was based on Iceland. Doug Chiang said DICE proposed the look, and Lucasfilm agreed: "[We wanted] to come up with something that could really complement what the other planets are. We knew in Battlefront that we were going to have a snow planet, a desert planet, and a forest planet. [sic] What else could we put in there to make it texturally more interesting? Iceland turned out to be a great candidate — the Icelandic lava flows. And that feel was very unique."

DICE's Audio Director Ben Minto recorded various sounds in Iceland, including bubbling mud pools, shrimp and cod grunts; or huge steel guy-wires from the Longwave radio mast Hellissandur.
