Star Wars After the Clone Wars
“After you have killed all the Jedi in the Temple, go to Mustafar system. Wipe out Viceroy Gunray and the other Separatist leaders. Once more the Sith will rule the galaxy! And we shall have… peace.”
―Darth Sidious to his new apprentice, Darth Vader.[src]
On Utapau, Grievous, along with the rest of the leaders of the Confederacy of Independent Systems, await instructions from Sidious. Soon enough, Sidious sends the Confederacy to the Mustafar system before Republic forces arrive. Not long after, Republic forces led by Obi-Wan Kenobi attacked the base. Kenobi managed to confront Grievous and the two began to fight. In the hassle, Kenobi managed to rip open the armor covering Grievous’ gut sack. The Jedi then shot it with the General’s blaster several times, killing the cyborg. The death of Grievous put Nute Gunray in charge. Meanwhile, on Coruscant Palpatine reveals to Skywalker that he is the Dark Lord of the Sith, prompting Skywalker to tell Jedi Master Mace Windu. Not long after, Mace Windu along with Kit Fisto, Saesee Tiin, and Agen Kolar attacked the Chancellor. Palpatine quickly admitted to this and killed Fisto, Tin, and Kolar. He later killed Mace Windu with the help of Anakin Skywalker, who needed Sidious to save his wife Padmé from death. The Sith quickly declared the Jedi the enemies of the Republic and sent out Order 66, which saw the clone troopers turning on their Jedi generals. Skywalker then surrendered to Sidious and the Sith Lord re-named him Darth Vader. Vader was sent to the Jedi Temple where he killed every Jedi left in it. On Utapau, Clone commander Cody ordered his men to fire upon Kenobi, but the Jedi survived this, however. On Kashyyyk, Commander Gree with another clone attempted to assassinate Grand Master Yoda, however the master beheaded the two with his lightsaber before they could blast him. Many other Jedi were killed during Order 66, including Ki-Adi-Mundi, Aayla Secura, Plo Koon, and Stass Allie. After murdering the Jedi on Coruscant, Vader headed to Mustafar to eliminate Nute Gunray and the rest of the leaders of the Confederacy of Independent Systems, who were hiding on the planet. The fallen Jedi turned Sith Lord then received a order from Sidious to send a shutdown signal that turned off all remaining Separatist droids, ending the war in the process.
