Crawler One was an icecrawler used on the planet Syned during the Republic Dark Age. It serviced the Arkadianate capital of Calimondretta. The Sith Lord Arkadia Calimondra used one of these icecrawlers to transport Jarrow Rusher back to the troopship Diligence since she intended to take the student refugees aboard the ship as Arkadianate subjects. It was piloted by a male Nazzar icecrawler driver. However, Rusher hijacked the vehicle and used it as a "trojan horse" during the Siege of Calimondretta. During the assault, "Crawler One" carried two artillery cannons including "Bitsy."
