Nur

Nur is an ocean moon in the Mustafar system in the Outer Rim. It is entirely covered by water with a high sodium content; no land areas have been recorded and no native sentient life is known, so the only known structure remained the underwater Fortress Inquisitorius.

After the incident on Coruscant, the moon was used as the headquarters of the Inquisitors and a place for holding captured Jedi. In 14 BBY, Jedi Knight Cal Kestis and Cere Junda infiltrated it, seeking to recover a holocron stolen by the Second Sister. In 9 BBY, the Third Sister, on Darth Vader's orders, launched probes from Nur to search for Obi-Wan Kenobi, and later brought the abducted Leia Organa to the moon; Kenobi and Tala Durith infiltrated the fortress and rescued her.
