By 19 BBY,[11] over a decade after the discovery of Anakin Skywalker, the spirit of the late Qui-Gon Jinn made contact with Yoda. After journeying to the planet Dagobah at Jinn's insistence,[4] Yoda discovered the birthplace of the midi-chlorians, where he learned of their role as the link between the Living Force and the Cosmic Force,[2] a connection embodied by five ethereal beings: Anger, Confusion, Joy, Sadness, and Serenity.[8]
