Thule

Thule is a semi-arid planet known for its rich savannas, continually bombarded by lightning storms, Thule was a hidden Sith stronghold. The rocky outcroppings which broke the plains were charred black from being hit by lightning. This charred rock later served as a form of sustenance for unusual, bioluminescent moss that made the rocks glow with an eerie light.

Ulic Qel Droma fought on Thule during The Great Sith War, during which the Dark Reaper was buried on the world. Thousands of years later, Count Dooku went to Thule to revive the Dark Reaper to attempt to destroy the Galactic Republic during the Clone Wars. A planetary shield enveloped the planet Thule, projected by the small moon Sivvi orbiting it.

The Battle of Thule is the last battle featured in the video game Star Wars: The Clone Wars. The battle was divided into four phases. At phase one, Anakin Skywalker and his strike force took out the planetary shield on the Thule Moon. At phase two, Obi-Wan Kenobi used the Low Altitude Assault Infantry Gunship to perform an aerial attack on significant strategic locations across planet Thule and destroyed the Communications Installation in order to cripple the Separatists' communications. At phase three, Mace Windu commanded the ground forces around Thule's capital city Kessia. Upon his arrival to Kessia, Cydon Prax destroyed Mace Windu's TX-150 Saber-class fighter tank. Mace Windu had to travel on foot to open the gates to the Sith Temple. At the final phase, Anakin Skywalker and his strike force went through the Sith Temple, defeated Cydon Prax and then re-defeated the Dark Reaper.
