Salissia was a location that shared its name with the Salissians, a group active in the galaxy during the Republic Era. The Nihil marauder organization attacked Salissia at some point after the Battle of Kur in 232 BBY. In a Senate meeting the following year, the Republic Senator Vaadu cited the attack on Salissia as one piece of evidence that the Nihil continuing to operate—presumed to be remnants of the group—still posed a threat to the upcoming Republic Fair being hosted on the Outer Rim planet Valo. However, Jedi Master Avar Kriss and the event's coordinator, Samera Ra-oon, countered Vaadu's argument by insisting enough security would be present, ultimately resulting in the Republic's Supreme Chancellor Lina Soh continued support for the Republic Fair's planning to continue.
