Following the Battle of Kur, the Nihil pirate group launched an assault on Salissia, which is situated within the galaxy, an event that transpired sometime in the period spanning 232 to 231 BBY. In the year 231 BBY, Republic Senator Vaadu was present at a Senate session that centered on the forthcoming Republic Fair on Valo, a planet located in the Outer Rim. He contended that the Salissia attack demonstrated the Nihil's ongoing danger to the Republic Fair. However, Jedi Master Avar Kriss and Samera Ra-oon, the coordinator for the event, assured him that ample security would be in place to guarantee its safety. Lina Soh, the Republic Supreme Chancellor, shared their viewpoint and proceeded with the meeting, notwithstanding Vaadu's worries.
The 2021 novel, The High Republic: The Rising Storm, penned by Cavan Scott, part of Phase I of the Star Wars: The High Republic initiative, makes reference to the Salissia attack.
