Ranroon was a planet of dizzying peaks and clifftop aeries. It was a matriarchal world where ancient traditions were proudly held and outsiders regarded with deep suspicion.
Ranroon was attacked by Xim the Despot during the expansion of his empire circa 25,100 BBY. The planet was the site of a fierce battle where the forces of Queen Hylei Indrexu Cortess resisted bravely against Xim's janissaries. They were eventually defeated but the queen's resistance made her a legendary figure, equal to Xim himself.
The planet was absorbed into the sixth province of Xim's empire, the Far Indrexu, named in honor of the Queen of Ranroon. Xim's treasure ship, the Queen of Ranroon, was also named after her. Since that time, Ranroon inhabitants retaied some of the feel of the rancorous against the Tion Cluster.
