The clash known as the Battle of Rishi transpired in the space surrounding the planet Rishi amidst the Galactic War. This war saw the Galactic Republic in opposition to the Sith Empire. With the help of their Nova Blades pirate cohorts, the Order of Revan strategically maneuvered both of the galactic superpowers into altering their patrol routes. This manipulation led to a head-to-head battle over Rishi, where Revan intended to annihilate both armadas by utilizing a Revanite fleet and Revanite operatives who had infiltrated the enemy ships. The Nova Blades deployed a signal-blocking device on the planet's surface, which severed all unauthorized communications between the planet and the fleets as soon as they entered orbit. Nevertheless, a small group composed of Imperial and Republic operatives successfully deactivated the Revanite signal jammer on Rishi. They were then able to send a warning to both fleets, which enabled both sides to apprehend the saboteurs within their own ranks and bring the conflict to a close.
The Battle of Rishi is portrayed in the Star Wars: The Old Republic MMORPG as a segment of the Shadow of Revan expansion's narrative. The specifics of the battle, notably the quantity of vessels on each side, fluctuate across different cutscenes, which complicates the process of achieving a precise enumeration.
