Ciri's TIE Advanced x1, formerly used by Darth Vader, during run in the trench
The Battle of Yavin was a major battle of the First War that led to the destruction of the first Death Star and Sera's first step to becoming a fully-fleged fighter pilot. It was one of many Allied major victories. With the imminent completion of the Axis's Death Star, the Alliance anticipated a major Imperial offensive. To unify command and coordinate a defense, the Mon Calamari Star Cruiser Independence and Babylon 5 carried members of the Alliance High Command to their base on Yavin 4.[20] Upon arrival, the Independence sent 70 squadron groups to the Yavin Base. Their numbers were augmented by veteran pilots as the Alliance gathered its resources in preparation for the coming battle.
