Fostin Nine, a satellite body, was situated in the Outer Rim and classified as a moon.
In the era of the Republic Dark Age, Beld Yulan, a mercenary, experienced the tragic loss of his offspring to a devastating disease on the moon; this drove him to despair and ultimately led to his induction into an Odionite death cult.
One thousand years afterward, in the time of the Clone Wars, Etain Tur-Mukan, who held the rank of Jedi General, gave the order for Omega Squad to conduct a scouting mission on the celestial body.
