The Charon Relay is a mass relay in the Sol system of the Local Cluster that orbits Pluto. Encased in a layer of ice hundreds of kilometers thick for thousands of years, the Charon Relay was originally believed to be nothing more than one of Pluto's moons. Following its discovery and reactivation by humanity in 2149, the Charon Relay has served as the point of access between Earth, the cultural and economic heart of human civilization, and the rest of the galaxy.
