Little is known about the ruling class of Xenotaur. They are the penultimate genetic modification, each a unique being of vast power. Each represents the greatest in physical and mental power developed through millennia of genetic manipulation and integration of conquered creatures. Kthuligarchy therefore refers more to the collective body of ruling members than to the individuals that make up that body.
What is known about the Kthuligarchy centers on their designs for Loar. From the time they were first discovered [in Sundered] they planned a full scale invasion to coincide with the arrival of their primary interstellar armada little more than three years out. They sent The Emissary to scout the world and prepare it for invasion from below ground.
