Welcome to the Echo Cluster, a dense cluster of star systems, rich in resources and native life. Over three hundred years ago the 11 races arrived marking the start of a complex and brutal history which is still unfolding today.

They brought with them a dangerous and powerful technology, which has allowed elite members of society to skip through time by accelerating close to the speed of light, slowing relative time and then decelerating to alter the course of history again and again. These people are commonly referred to as Echos.
