The limited engagement that occurred on Belsavis, known as the attack on Belsavis, took place in the Plawal Rift area of the world Belsavis during the year 18 BBY. Following Order 66, a small group of Jedi refugees, primarily younglings, were being protected by the Ho'Din Jedi Master named Plett within the Plawal Rift. When Emperor Palpatine discovered this hidden sanctuary, he ordered its destruction using the battlemoon Eye of Palpatine. Nevertheless, Jedi Knights Callista Masana and Geith Eris successfully crippled the battlemoon within the Moonflower Nebula. Although an Imperial squadron of starfighters then attacked the refuge, the refugees were able to flee because they had advance notice of the impending assault.
