The Guavian Ship was model of starship that was used by the Guavian Death Gang during the war between the First Order and the Resistance.
A contingent of Guavian starships fought in a skirmish in Guavian Death Space after the Colossus intruded on their territory, though most were destroyed.
In 35 ABY, Guavian starships were part of a fleet assembled by Lando Calrissian to assist the Resistance during the battle against the Sith Eternal forces over the planet Exegol.
