Aru-Wen was a Jedi Knight of the male persuasion that became a member of Lord Hoth's Army of Light and participated in the battles on Ruusan. He opted to leave his Padawan, named Set Harth, on Coruscant instead of bringing him to war. On Ruusan, Aru-Wen met his death when Lord Kaan's thought bomb detonated. Following Aru-Wen's demise, his Padawan Set Harth abandoned the Jedi Order and embraced the path of a Dark Jedi.
