Kavil's Corsairs were a group of Imperial privateers operating in the months after the Battle of Endor. They were based on Axxila and maintained a fleet of TYE-wings, Z-'ceptors, a BTL-S3 Y-wing, and at least one flight cruiser decorated with the Blazing Claw. Their other targets included Edusa and Vandyne.
They were led by Kavil, who was tempted by the possibility of social elevation in the Empire through his duties.
After being driven off of Eiattu 6, Moff Leonia Tavira joined with Kavil's Corsairs. She intended to overthrow Kavil with support from the New Republic, and to this end kidnapped Tycho Celchu and "Leia Organa". Presumably the Corsairs later became part of her Invids organization.
