Ottau was a Human male who worked for the Republic Strategic Information Service during the Cold War against the Sith Empire. In 3643 BBY, General Var Suthra tasked Ottau with tracing a transmission from the Sith Lord Darth Angral, which Ottau tracked to a secret Imperial listening post on the planet Ord Mantell. Ottau then passed on his reconnaissance to a Jedi Knight sent by Suthra, and the Jedi attacked the listening post, recovering valuable data.
