Stranded in his X-Wing, Luke reads a story from the journal of Ben Kenobi about a time that Master Yoda was on a mission to a planet with an apparent population entirely made up of children who wield a mysterious “stonepower.” To get to the heart of the mystery of the children and their obsession, Yoda must delve deep into the heart of the mountain. The story pays off in the present timeline as Luke must take his knowledge of Yoda’s mission to defeat the great evil unveiled in Yoda’s journey.
