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.

One of the battles on Ruusan appeared in the artwork by Wayne Lo titled "Unused Jedi Temple mosaic" for the second season of the Star Wars: The Clone Wars television series. It was included in the production journal of the Star Wars: The Clone Wars The Complete Season Two. The concept art also depicted Valenthyne Farfalla leading the Army of Light, Lord Hoth and the death of Pernicar. Parts of the mosaic can be seen, which includes the battle, in a room in "Lightsaber Lost," the eleventh episode of the second season of the series.
