Oosalon

Oosalon was a mountainous planet located in the galaxy's Outer Rim Territories. During the early rebellion against the Galactic Empire, two rebels&mdash;the Jedi Kanan Jarrus and his Padawan, Ezra Bridger&mdash;scouted Oosalon as a potential location for a rebel base. Instead, they were confronted by two Imperial Inquisitors, the Seventh Sister and the Fifth Brother, and engaged them in a lightsaber duel on Oosalon Mesa before escaping.
