Mission to Mustafar (Smashb1996)

"Obi-Wan and I have been given a very important mission by the Council. The Separatist leaders are hiding on Mustafar; we are going on a mission there, to capture them, and put an end to this war. I will return safely, my love; I promise."

- Anakin Skywalker to Padmé Amidala, before the former leaves for Mustafar

In 18 BBY, the Dark Lord of the Sith, Darth Sidious, better known as Palpatine, the Supreme Chancellor of the Galactic Republic, was revealed to have started the Clone Wars in order to seize control of the Republic and destroy the Jedi Order. Palpatine, his true identity exposed, and his master plan foiled, managed to escape Coruscant, and flee known space. As a result, the Jedi High Council was forced to take control of the Galactic Senate until a new Chancellor could be elected.

Even though the primary threat was over, the Jedi Council determined that the last of the Separatist leaders had to be rounded up, so that the war could be brought to an official end. In order to accomplish this, the Council sent Jedi Master Obi-Wan Kenobi and Jedi Knight Anakin Skywalker, regarded as the best duo in the Order, to capture the members of the Separatist Council and bring them back to Coruscant for questioning and trial.

WIth their new prototype spacecraft, the Beta 8A Jedi Starfighter, which housed two people, and had a cloaking device, Kenobi and Skywalker traveled to Mustafar, infiltrating the Separatists' base, the Klegger Corp Mining Facility, and sabotaging essential systems to make the Separatists easier to capture.

When the bases' defenses were completely rendered useless by the Jedi, they called the 501st Legion, the most elite group of clone troopers in the Grand Army of the Republic, to finish the job. When they arrived, they easily overwhelmed the droid and Neimoidian forces stationed at the facility, allowing Kenobi and Skywalker to capture the members of the Separatist Council, with barely any effort.

With the Separatist leaders captured, Kenobi sent a deactivation signal to all Separatist droid units, of which a very large amount of the CIS forces were made up of, and 99% of the Separatists planets and forts were forced to surrender to Republic forces, and the Clone Wars, one of the largest galactic conflicts of all time, was finally put to an end.

Prelude
"Great care, we must take."

- Yoda, on the Sith threat

Sidious revealed
"He won't give up his power; I've just learned a terrible truth: Chancellor Palpatine is a Sith Lord." "A Sith Lord?!" "Yes, the one we've been looking for."

- Anakin Skywalker and Mace Windu discuss the revalation of Darth Sidious' identity



A few days before the mission's inception, Jedi Knight Anakin Skywalker uncovered a shocking revalation about Darth Sidious' identity: he was none other than Chancellor Palpatine, leader of the Galactic Senate, and Skywalker's mentor. Upon this discovery, Skywalker reported this discovery to Master Mace Windu, who, along with fellow masters Kit Fisto, Saesee Tiin, and Agen Kolar, went to the Chancellor's offices at the Republic Executive Building to arrest him; relieving him of power.

When the Jedi confronted Palpatine, a lightsaber duel broke out, and all 4 Jedi were felled by the dark lord. However, shortly after Mace Windu's death, Skywalker, Obi-Wan Kenobi, and Jedi Grand Master Yoda made their way into the Chancellor's suite. There, Sidious was forced to flee; he was simply over-matched against three of the most powerful Jedi in the galaxy, and Skywalker, whom Sidious had sought to turn to that dark side for the past thirteen years, rejected it completely.

After the flight of Sidious, the senate was placed under the temporary control of the Jedi Council, who sought to capture the members of the Separatist Council, which would end the war, and elections could be held for a new Supreme Chancellor.

Finding the Separatist leadership was easier said than done; as Kenobi, after the Battle of Utapau, had discovered information from the Separatist base on Utapau of the Separatist Council's whereabouts: Mustafar.

Last days of the CIS
During the Confederacy of Independent Systems' attack on the galactic capital, Coruscant, Count Dooku, the Head of State of the Separatist Council and the Confederacy, was killed by Skywalker, which greatly pleased Palpatine, in actuality Dooku's master, Darth Sidous, who saw this as a sign of the young Jedi's power. Sidious now knew that his plan of turning Skywalker to the dark side was unfolding, since Sidious felt he knew how to mold Skywalker into his next Sith apprentice.

Following Dooku's death, General Grievous, the Supreme Commander of the Separatist Droid Army, assumed direct control over the Council, which at the time was based on the sinkhole planet of Utapau.

Grievous's first action under Sidious's guidance, was the Council's transfer from Utapau to Mustafar, as Sidious knew of the impending offensive on Utapau led by General Obi-Wan Kenobi. Once on the volcanic planet, the Council settled itself into the Klegger Corp Mining Facility. The facility was clandestine, perfect for hiding in; but Kenobi, once he destroyed Grievous, was able to find this secret base, discovering that all the members of the Separatist Council would be there.
