The year 3643 before the Battle of Yavin (BBY) was a period of time during the Cold War between the Galactic Republic and the Sith Empire. Better known during that time as year 10 after the Treaty of Coruscant (ATC), the events of the year featured renewed conflict between agents of the two superpowers and heightened tensions throughout the galaxy. Various events, such as the Desolator crisis, the defection of the Republic's Havoc Squad, an attack on the Republic cruiser Esseles, and many other conflicts continued to add to the political anxieties of the last decade.
