Xin

The Xin are the name given to the mostly unknown enemy responsible for the Sliming of Home two centuries ago. Not much is known about them except all attempts to communicate with them failed and the completely unprovoked attack was swift and near-genocidal.
Numerous efforts have occurred to find the Xin as Resoni cautiously ventured back into the stars. Though numerous theories abound, the greatest leads have been found in the Fringes and has been one of the key catalysts of growth for ARM University.
