The Eyttyrmin Batiiv was a pirate group that emerged shortly after the formation of the Galactic Empire. They were fairly successful for some time, until the Empire crushed them at the Battle of Khuiumin.

Of the group's eight thousand members, less than three hundred survived the battle—less than three percent. The remnants, who came to be known as the Khuiumin Survivors, eventually settled on the planet Courkrus, doing occasional work with Leonia Tavira's Invids.
