Empress Teta system
The Empress Teta system or Teta system located in the Teta sector in the Deep Core, named for Empress Teta, contained the planet of Empress Teta (formerly Koros Major). It was formerly known as the Koros system, and was colonized by Coruscanti explorers on generation ships. One of the places in the galaxy where carbonite could be found, its discovery brought up the technology of sleeper ships.
The History of the system was recorded in the Tedryn Holocron.
