Telos IV or Telos is a planet in the outer rim. It was nearly destroyed in the Jedi Civil War
Before the Jedi Civil War was a planet rivaling Coruscant, and an important Old Republic and Jedi military base. During the Jedi Civil War, Darth Malak ordered the bombardment of the planet causing catostrophic destruction. Jedi affiliated, military and political areas were targeted. The facilities at the northen polar ice cap were left untouched.
The planet was then set to be restored by several parties such as the Czerka Corporation and the Ithorians. The Citadel Station was the main base for the restoration, which also helped remove any harmful substances from the atmosphere. The Jedi Exiles decisions on wether to help Czerka or the Ithorians affects who takes over the project.
The Jedi Exile later returns to Telos as it fell under attack by the Sith forces under Darth Nihilus. She helped the Telos Security Force and the united Mandalorian clans as well as with members of the Onderon Military to fight to Ravager, Nihilus's flagship. The Exile and her companions were successful in killing Darth Nihilus and destroying his ship.
