Patraleias was a Sith Lord that lived during Darth Plagueis time. He was a born Anzati and his skill was what made him so special for Darth Sidious and Plagueis. Both Sidious and Plagueis saw Patraleias as a servant so they were never afraid of his reaction to their acts. Patraleias was born on 100 BBY, but by good diet he managed to keep his health until 0 BBY. He was the most dangerous of assassins and he was often watched by Jedi. But the Jedi that watched him, often fell victims when they were caught. At the end of the century Patraleias was still serving Darth Sidious and without second thought he continued to serve him. He was killed after dueling with Valens Silvertongue, a skilled Jedi and Cassus Skywalker's Padawan.
