The Wellspring of Life, a mystical world located in the center of the galaxy, was the birthplace of a microscopic species that served as the link between the Living Force[3] within all life forms and the infinite Cosmic Force.[8] It was also the foundation of life,[3] with all life forms serving a symbiotic host for the living organisms[1] native to the wellspring.[3] In modern science these intelligent microbes became known as "midi-chlorians."[9]
