- "The galaxy has changed—it's mine for the taking! I will rule the Empire…I will sit on Palpatine's throne."
- ―Carnor Jax — Listen (file info)[src]
Carnor Jax was a Royal Guard and aspiring Sith Lord who made a bid for the vacant Imperial throne. Jax was the second Sith apprentice to the self-proclaimed Dark Lady of the Sith, Lumiya, and served her after the deaths of Darth Vader and Emperor Palpatine. Jax and Lumiya were responsible for the extermination of the last few remaining Prophets of the Dark Side on Bosthirda.
After Palpatine returned in the form of several clone bodies, Carnor Jax succeeded in ensuring the demise of the last of Palpatine's clones, thus murdering the Emperor and opening a path to the throne. Jax was also responsible for the destruction of the Royal Guard, and had all but one of them killed off in a surprise attack on the planet Yinchorr. The remaining member, Kir Kanos, became a fugitive, forcing Jax to concentrate his efforts on capturing the man. The chase led Jax to capturing the Rebel leader Mirith Sinn and subjecting her to torture.
However, in an unfortunate series of events, the actions of Kanos helped Sinn to escape, and Jax and Kanos found themselves in a final showdown on Yinchorr. The following battle was evenly matched, but the unexpected prowess of Kanos threw off the balance and Jax was killed. Carnor Jax's death left Lumiya without a known apprentice for almost 30 years.
