The Eoki were a sentient species from the planet Eoki, just beyond the N'Akkiarlian Capital Systems in the N'Akkiarl Galaxy. By the time of the N'Akkiarlian colonisation of part of "the galaxy" in 5,000,000 BBY they had been extinct for nearly 15 million years. It was widely believed they towght the early N'Akkiarlians interstellar travel, it is also believed that before the N'Akkiarlians evolved the Eoki controlled the N'Akkiarl System and enslaved the N'Akkiarla almost immediately after they had evolved. It was during their time as slaves the N'Akkiarla learned about space travel from there Eoki masters.
