Etlan

The Etlans were a sentient species with the physiological classification DBDG, and the dominant race of the Etlan Empire.

Their physical appearance was so similar to that of Earth-humans that they could easily pose for each other.

There were theories about a prehistoric colonization program by common, star-travelling ancestors of Etlans and Humans. Attempts at procreation between the two DBDG species, however, remained unsuccessful.
