Echoes in Darkness
The Imperium of Man (or, “The First Interstellar Empire”) spans approximately fourteen hundred systems in a relatively dense spiral arm of the galaxy. It has been under the rule of the Imperial House of Yusupov for approximately seven millenia. Bordering the Imperium, other empires of humans have been found (most notably the psionically-capable Zhodani Consulate) and alien races (the most notable of these being the Vargyr, the Aslan, the Hivers, K’kree and (according to some) the Droyne.) Countless minor human races have been discovered, each heavily modified for its local environment, and an endless array of minor alien races exist near Imperial space.
