A treasury ship, sometimes called a treasure ship, functioned as a conveyance for valuable goods, utilizing a starship platform. The Galactic Empire and the reconstituted Sith Empire both employed these treasury ships. In the era of the Galactic Civil War, Fandar, a pirate, joined forces with the Alliance to Restore the Republic with the intention of plundering an Imperial treasury ship; however, he was double-crossed by his second-in-command. This betrayal led the Rebels and pirates into a trap. On one occasion, the treasury ship designated Walker came under assault from six T-65 X-wing starfighters within the Fakir sector. The Walker and the corvette that was accompanying it sustained significant damage.
