Widely used by the Jedi Order, The Seltaya-class fast courier was a sleek yet durable scoutship, equipped with tail and wingtip mounted engines, and equipped with a protective laminate that could endure impressive punishment - ranging from laser cannon fire to several direct proton torpedo impacts - and still manage to make it home.
Unlike many fighters of the period, the Seltaya was equipped with an internal hyperdrive. It could be flown by a single pilot and/or an R2-series astromech droid, and at least some models had a cockpit entered via an opening canopy. Some ships of this class also had relatively expansive on-board accommodation, including a galley, room for at least four additional passengers or crew alongside the pilot, and a crew area with a view-screen.
The Jedi Order kept a number of these ships in the hangars at the Jedi Temple on Coruscant, including the Limit of Vision which Jai Maruk used to scout the Hydian Way, and the ship which Palleus Chuff took to Ithor while impersonating Yoda. Although some people questioned the quality of construction of war-built ships, with each part contracted out to the lowest bidder, the streamlined Seltayas were among the favorite ships of Chief Technician Boz Addle at the Temple.
The Seltaya-class ship which Palleus Chuff takes to Ithor early in Yoda: Dark Rendezvous appears to be a new, single-seat military starfighter built during the Clone Wars. However, the real Yoda and four other Jedi return to Coruscant at the end of the novel in another vessel identified as a Seltaya, this time said to be an older ship, bought second-hand on the Hydian Way: this ship has apparently been in civilian ownership, and seems larger, with a cockpit large enough for at least two people, a galley, and some sort of crew area equipped with a viewscreen, said to be at the opposite end of the ship from the cockpit.
It is not explained in the novel if the two ships are supposed to have precisely the same configuration, or if the variation between the two ships is a difference between military and civilian models.
