More than two dozen moons orbit the Outer Rim gas giant Yavin. Of those moons, the one designated Yavin 4 is by far the most habitable, supporting a vast array of flora and fauna within its lush and endless jungles.
Yavin 4 also holds a great deal of interest to the Jedi and the Sith. For well over a thousand years now, the dark side of the Force has flowed through Yavin 4 in an ever-increasing magnitude.
