Omhotar Empire

During the time of the Ancients, a vast empire grew throughout Primea , known to scholars as the Omhotar Empire.
Omhotar is translated as "The Higher People".  The empire spanned nearly all the human planets in the Primea system. Its capital was Kanatoph on Mot-Kaph (now known as Orbis Vecnar) and quite famously the birth place of Vecna. Around 800 BCE The empire was taken over by Vecna, and by 700 BCE Vecna was defeated and by 670 BCE the Omhotar (and last Ancients empire) collapsed.
