The Vault

"The Vault" was a top secret safehouse on Agamar, accessible through a lift in the basement of the capital building. It was an expansive underground chamber in which the rich could buy out apartments where they would be safe and isolated from the rest of the galaxy. It was considered to be the safest place in the galaxy.

Palpatine owned a suite in the lowermost level of the vault. In 20 BBY, a Gand group led by Zuckuss captured the capital building and gained access to the Vault. The group, promised "freedom" from Zuckuss, betrayed their leader when they discovered that his goal was to steal a sensitive datadisk from Palpatine's apartment containing proof of his double life as Darth Sidious, instead locking him in the apartment and telling the Confederacy of Independent Systems of the Vault's location. When a clone trooper force led by Kote arrived, it would lead to the Battle of the Vault and an assassination attempt on the chancellor.

Behind the scenes
The Vault, created by Star Wars Fanon Wiki user DjMack, is inspired by the author's bathroom, which is where most of his Star Wars fantasies and action figure battles took place as a child.
