Secret mission to Geonosis

"The Droid Gotra heard about a surviving Geonosian queen with a droid factory. They wanted me to liberate it from the evil carbon-based oppression. But we can always steal it for us, eh?"

- Doctor Aphra and Darth Vader

The secret mission to Geonosis was carried out by the Sith Lord Darth Vader not long after the Battle of Yavin. Having fallen out of favor with Emperor Palpatine, Vader had recruited the rogue archaeologist Doctor Aphra and the assassin droids BT-1 and 0-0-0 to assist him in building an army of unquestionably loyal battle droids. Vader soon arrived on Geonosis and his team infiltrated the lair of a Geonosian queen who had utilized a droid factory to produce battle droids as her "children" after she was injured and left unable to produce offspring during the Sterilization of Geonosis. While BT-1 fired on the queen's B1 battle droids, Vader and Aphra severed the queen from her factory, and Aphra used her starship, the Ark Angel, to blow a large hole in the roof of the lair so that Vader's own starship could then extract both the factory and Vader's team with a large crane. The captured droid factory began producing BX-series droid commandos for Vader, which he used to assault the research base of a rival Imperial operative named Cylo-IV.

Prelude
"I need troops of unquestioning loyalty.''" "Hey, I understand. Who wouldn't a phalanx of carefully restored battle droids&hellip; How do you feel about a secret mission to Geonosis, Lord Vader?" "I have no feeling regarding Geonosis." "''Good."

- Aphra and Darth Vader plan the mission

During the reign of the Galactic Empire, the Empire sterilized the planet Geonosis, killing nearly all life on Geonosis except for a single insectoid Geonosian queen who was left injured and unable to produce offspring. She took up residence in a lair and attached herself to a droid factory to try and continue her race, using the factory as her womb and the battle droids it produced as her "children."

Some time later, during the Galactic Civil War between the Empire and the Alliance to Restore the Republic, the Alliance destroyed the Empire's greatest weapon: the Death Star mobile battle station capable of destroying entire planets. One of the Rebels' follow-up campaigns included an assault on Weapons Factory Alpha, the Empire's largest weapons factory on Cymoon 1, and the Dark Lord of Sith Darth Vader failed to prevent the Rebels from blowing up the factory. Emperor Palpatine, Vader's Sith Master, grew displeased with Vader and demoted him for his failures at Yavin and Cymoon 1 and put him under the command of Grand General Cassio Tagge. Vader secretly hired two bounty hunters to hunt down an Imperial operative who Vader had seen working for Sidious and the Rebel pilot who had destroyed both the Death Star and Weapons Factory Alpha, before meeting Tagge aboard his Super Star Destroyer Annihilator.

Vader and Tagge soon attacked and defeated a group of pirates who utilized custom droideka security droids provided to them by a Doctor Aphra. Vader had been impressed with the droidekas and sought her out, finding her on Quarantine World III and recruiting her help. The archaeologist also gave Vader two assassin droids, 0-0-0&mdash;commonly known as Triple-Zero&mdash;and BT-1 to help. Vader revealed that he needed private resources of his own to capture the operative and the Rebel: unquestionably loyal battle droids. Aphra understood, and knew of the Geonosian queen who had survived her homeworld's sterilization and possessed a droid factory. Vader agreed to her choice, and they left for the old warzone of Geonosis aboard Aphra's starship, the Ark Angel.

The mission
"And now for our devilishly clever plan to steal a robot womb factory off a homicidally broody alien queen. Do you still think this is a good idea, Lord Vader?''" "''Yes."

- Aphra and Darth Vader, as they begin the heist While en route to Geonosis, Vader brought in his J-type 327 Nubian starship to aid in the latter stages of the mission. Soon thereafter, the Ark Angel set down near the entrance to the queen's lair, while Aphra sent Triple Zero and BT into the cavern to scout out the most direct route to the queen's chamber. Vader had been to Geonosis several times before during the Clone Wars while still a Jedi Knight, and being on the red-desert world brought up painful memories of his deceased wife. So he ordered Aphra&mdash;who had been asking Vader personal questions&mdash;to be silent as they, too, entered the catacombs to steal the droid factory.

Farther in the tunnels, BT and Triple Zero came across several of the queen's B1 battle droids, and BT promptly destroyed them with its flamethrower while Triple-Zero insulted them in their native language. Aphra and Vader soon came across the carnage. Aphra examined the burned droids, noting that they had "interesting tweaks," to the standard battle droid design; such as insectoid wings which Geonosians often supported. Aphra conflated that the "tweaks" meant the queen did not see the droids as droids, but as her own children. Vader and Aphra caught up with the two assassin droids and they together entered the queen's chamber.

Vader ignored the queen's objections, and leaped down to the queen and cut her from the droid factory&mdash;her "womb"&mdash;using his lightsaber. She survived the attack and sent dozens of B1 battle droids, some capable of flight, to stop the Dark Lord. In response to this, Vader ordered BT to open fire. The droid did so with his built in chainguns and blasters, pulverizing many of the droids while Vader cut down others. Aphra, meanwhile, prepared the Ark Angel locator beacon to send it to the ceiling of the lair. When the beacon's thrusters malfunctioned, Aphra jumped down to Vader's position to ask if he could help. Before the rogue archaeologist could finish asking, Vader used the Force to throw the beacon to the roof with the point of his finger, leaving Aphra content with the Sith Lord's abilities.

The Ark Angel, at Aphra's order, barraged the roof of the lair, creating a massive hole in the ceiling and causing vast amounts of rock to rain down. However, Vader used the Force to create a "bubble" around himself and the doctor to protect themselves while Vader's Nubian starship lowered a crane through the hole. The queen continued to order the battle droids to stop Vader and bring back her "womb", warning them that her self-made empire would never end. Aphra attached the crane to the droid factory while Vader held off the queen's onslaught. Aphra was unsure if Vader's "pretty little" starship would be able to rip the factory from its foundations, but Vader assured him it would due to the "enhancements" he had given it. And it did, lifting Vader, Aphra, and the factory into the skies of Geonosis while BT and Triple Zero followed behind using BT's booster rockets.

Aftermath
"In a few hours you'll have your droid army. Some minor tweaks to get it 100%, but nothing BT can't handle."

- Aphra to Vader, after starting the droid factory

Vader and his team returned to his Nubian, docked with the Ark Angel, and began fine-tuning the droid factory. Not long after, BT and Aphra got it working successfully, creating a single BX-series commando droid that Triple Zero examined. Aphra remarked that Vader now had a private off-the-grid army and no longer needed her services, thinking he would kill her. Vader, however, believed she was still useful and informed her that she would live as long as he had use for her. Soon, one of the bounty hunters Vader had hired, the Wookiee Black Krrsantan, came with a very important delivery.

Krrsantan soon captured Cylo-IV and brought him aboard where Vader ordered Triple-Zero, a specialist in torture, to learn what Sidious had tasked him with. Triple-Zero did so and was able to identify the agent and the location of his research base where assassins were being trained to possibly replace Vader as the Emperor's enforcer&mdash;with commission from Darth Sidious himself. The protocol droid accidentally killed Cylo-IV during the interrogation, and informed Vader of his findings. Vader ordered the course to the base be set, and they left immediately to storm the base using two platoons of the newly built commando droids.

Behind the scenes
"But for this he will need his own personal forces. Vader recruits droid archaeologist Doctor Aphra to do so&mdash;and she lead the fallen Jedi to the old warzone of Geonosis&hellip;"
