Hypori/Legends

Hypori was a temperate planet of small oceans and rocky landscapes located in the Ferra sector of the Outer Rim Territories, notable for being a heavy battle droid producer.

Geology
The planet had no native population, but following the Invasion of Naboo, Hypori was transformed into a foundry world for the Confederacy of Independent Systems. The planet was located near Geonosis, another world hosting Techno Union droid factories, and an entire hive of Geonosian workers was relocated to Hypori in a sponsored effort by Baktoid Armor Workshop to construct and maintain the new Separatist facilities. The tough bedrock and soil proved difficult to assimilate into a true and proper hive-mound, though the Geonosian workers eventually created huge underground factories. The existence of these droid factories was kept secret from the Galactic Republic during the lead-up to the Clone Wars.

Sith training ground
In 54 BBY, Dark Lord of the Sith Darth Plagueis trained his apprentice Darth Sidious on Hypori with assassin droids.

In 37 BBY, During Darth Maul's training under the command of Darth Sidious, the Nightbrother spent a month in the planet without food or water and with a horde of assassin droids as company. After that, Sidious returned to fight against Maul, depriving him of his lightsaber. When Maul began filling his hatred for Sidious and tried to kill him, the human appraised him for passing the final test. Maul was given the title of Sith Lord, secretly against Darth Plagueis' wishes.

Clone Wars
Shortly after the onset of the Clone Wars, Jedi Master Daakman Barrek and his Padawan, Sha'a Gi, uncovered the Separatist operations on Hypori during an intelligence-gathering mission in the sector. They reported back to the Jedi High Council on Coruscant, which dispatched a Jedi and clone trooper strike team to investigate further.

Unfortunately for the Republic forces, the Separatists had not left Hypori undefended. Disguised orbital mines seeded in orbit crippled much of the task force, and the surviving Jedi&mdash;among them Ki-Adi-Mundi, Shaak Ti, K'Kruhk, Tarr Seir, Sha'a Gi, and Aayla Secura&mdash;were ambushed by legions of B2 super battle droids and OG-9 homing spider droids led by General Grievous. The ruined hull of an Acclamator I-class assault ship that had crashed into Hypori's surface became the site of an epic battle between the droid commander and the Jedi, from which only four Jedi emerged alive, with the help of ARC Captain Fordo and the Muunilinst 10. The Jedi had planned to attack Grievous,only to realize they were going the wrong way. Sha'a Gi's fear led him to his death,as Grievous dropped from the sky. Tarr Seirr was the first one to attack,his head crushed in the process. K'kruhk was next,suffering a near-fatal blow,he was only hibernating. Aayla Secura was tossed aside,and Shaak Ti was hit in the shoulder. Ki-Adi-Mundi being the last Jedi standing,he quickly charged the Kaleesh warrior. seconds later,a gunship chased the cyborg away. Mundi leapt onto the ship,discovering that the two female Jedi could be alright. Though some of the battle droids were destroyed during the rescue attempt, the droid factories on Hypori remained in operation, and at least one remained operational after Darth Vader ordered the deactivation of the Separatist droid armies from Mustafar in 19 BBY.

Galactic Civil War
The planet was abandoned until the Hutt Cartel learned of the existence of a droid factory that had survived the Clone Wars. They lured the Zann Consortium to the planet's surface, hoping that Tyber Zann's army would deactivate the hostile droideka Mark IIs, thus ensuring that Jabba the Hutt's forces could land and gain control of the planet&mdash;in the process killing Zann himself. However, the plan backfired, and cost Jabba greatly. The Consortium then used the technology on this planet to produce droideka Mark IIs. In the aftermath, Jabba and Zann agreed to a ceasefire.
