Tsealsir was built for the Culture and then given as a present to a Megaship on Vavatch Orbital rather than upgraded. The shuttle used cameras to see what was going on within it. When the Orbital was slated for destruction during the Idiran-Culture War it returned to Culture service and sent to evacuate the Eaters. The Eaters refused to board but Tsealsir was instructed not to leave until the last moment. Horza sold the shuttle for five Aoish Tenths at Evanauth.
