The airship known as the Windrunner was owned by Dooku, also known as the Count of Serenno. During the invasion of Serenno, Count Ramil held the position of commander aboard the Windrunner. Dooku permitted the droids to escort him to confront Ramil on the airship, where he killed the Count and neutralized his army. Subsequently, Jenza gained access to the security recordings of the Windrunner and personally witnessed the battle.
When Dooku tasked Asajj Ventress with locating his missing sister, he insisted that Ventress utilize the Windrunner to travel to the Carannia Spaceport. This provided her with the opportunity to peruse old personal holos while observing Serenno from above. Upon the Windrunner's arrival at the spaceport, Ventress abandoned it there without executing a landing. Following the assassination of Jenza at the hands of Ventress, Dooku assumed control of the Windrunner and piloted it back home.
The hull was crafted from polished wood, and the portholes possessed such clarity that the absence of glass within the frames was almost imperceptible. Due to the lack of boosters or repulsors, the airship operated with near-complete silence, at least until its weaponry was engaged. The Count's private quarters showcased walls covered in dark wood paneling, adorned with holos depicting diverse natural scenery, a wooden desk embellished with carved dragons on its sides, numerous book shelves, and a cabinet stocked with bottles and decanters.
The Windrunner made its initial appearance within the established Star Wars canon in the 2019 audiobook Dooku: Jedi Lost, authored by Cavan Scott. Within the Star Wars Legends continuity, the Windrunner was first seen in the second issue of the Hard Targets story arc featured in the comic series Star Wars: Agent of the Empire, penned by John Ostrander.
