2500 BBY

The year 2500 before the Battle of Yavin was a period of time in the era between the Old Sith Wars and the New Sith Wars. Around that time, prospectors discovered that the core of Yavin Prime has fused hydrogen and carbon into Corusca gems, sparking a mining rush that dies out less than a century later. Also around that time, the main hall of the Jedi Archives is constructed in the Jedi Temple on Coruscant. That iteration of the Archives remains unchanged for 2,500 years.
