A Force-sensitive individual resided on the world of Ruusan at some point during the New Sith Wars, specifically between the years 1002 BBY and 1000 BBY. Although this person was sensitive to the Force, their skill in utilizing its abilities was considered average for the era. Still, the Force-user participated to some extent in the Ruusan campaign, a sequence of conflicts between the Army of Light of the Jedi Order and a Sith group known as the Brotherhood of Darkness.
While on Ruusan, the Force-user came across Darth Rivan, a Dark Lord of the Sith who had unknowingly been moved ahead in time and was entirely cut off from the Force. This event was caused by the evil influence of the Darkstaff, a Sith relic that the Dark Lord once possessed. The Force-user, after meeting Darth Rivan, was able to eliminate the greatly weakened Dark Lord of the Sith.
