Archaeological dig on Yavin 4

Before the conflict known as the Battle of Coruscant, an archaeological excavation was conducted on the moon Yavin 4. During this excavation, the Great Sith Wars Bas-Relief was discovered within one of the massive stone temples erected by the Massassi upon the moon approximately five millennia years prior to the ascent of the Galactic Empire.

Subsequently, Darth Sidious, a Dark Lord of the Sith, who was publicly known as Supreme Chancellor Sheev Palpatine of the Galactic Republic, recovered the Great Sith Wars Bas-Relief from the Yavin 4 archaeological location.
