Alastar Treen, a Human Senator of the male persuasion, served as the representative for Corulag within the Galactic Senate as the Republic's time drew to a close. In the time before the battle of Geonosis in 22 BBY, the Confederacy of Independent Systems tried to murder him. Sia-Lan Wezz, Rorworr, Arani Korden, together with a band of adventurers, rescued him, and the assassination failed. Following his death at the hands of the Separatists at the outset of the Clone Wars, he was succeeded by Zafiel Snopps.
