Star Wars: Shades of Good and Evil
Battle of Yavin
The Battle of Yavin was a major battle of the Galactic Civil War that led to the destruction of the first Death Star and Luke Skywalker’s first step to becoming a fully-fledged Jedi. It was one of the Rebellion’s first major victories.
It is used as a major marker for dating events that occur in the Star Wars Universe. Events are usually dated BBY (Before the Battle of Yavin) or ABY (After the Battle of Yavin) as this an easily fixed point in the timeline and cannon.
