The Geist, a Mon Calamari cruiser, had General Hera Syndulla as its captain. During the assault by the Galactic Empire at the Mako-Ta Space Docks, it was stationed there. It managed to be among the small number of cruisers that survived the onslaught.
The term "Geist" originates from the German language, translating to "Ghost." This was also the designation of Hera Syndulla's personal VCX-100 light freighter featured in the Star Wars Rebels animated program.
