Ziost

Ziost was a planet located in the galaxy's Outer Rim Territories in grid square R-4 on the Standard Galactic Grid. It was one of the noteworthy worlds of the ancient Sith.

As mentioned by the Jedi writer Kli the Elder in the Rammahgon, Ziost once had a fertile environment, until the Sith established their presence there and laid waste to the planet just as they did with Moraband, Exegol, and Asog. In the time of the Galactic Republic, Ziost was quarantined along with the likes of Malachor, Jaguada, and Rhelg, and its affiliation to the Sith was hidden from history.

Ziost was the original site of an ancient Sith ritual altar that was present in the Grand Republic Medical Facility on Coruscant in 19 BBY. Around 1 BBY, CR-8R considered Fortress Vader on the planet Mustafar the spookiest Imperial stronghold this side of Ziost.
