The Yawnor served as a Delta-class JV-7 escort shuttle utilized by the people of Ripoblus throughout the duration of the Sepan Civil War. In the midst of the First Battle of the Sepan system, this very Escort Shuttle was deployed with the purpose of thwarting the capture of Modular conveyor group Asbo. This group held critical war materials, notably Imperial munitions, suspected to have been sold by Admiral Harkov, who, in a twist of fate, spearheaded the very seizure it was meant to prevent. The Escort Shuttle tried to eliminate Stormtrooper transports group Epsilon, however it was ultimately downed by the forces of the Empire.
