Battle on Ruusan

At some point in galactic history, a series of battles were fought on Ruusan, leaving behind relic-strewn battlefields that would remain years after. A room in the Jedi Temple on Coruscant was decorated with stained glass windows, one of which depicted one of the battles on Ruusan. The former Pirate Queen Maz Kanata mentioned the battles in the book that became known as the Smuggler's Guide.
