The Gil'Dishpan are the oldest and most powerful, imperialistic, space-faring, aquatic extraterrestrial race in the universe. They appear to be purple giant tube worms, and are powerful telepaths. The Gil'Dishpan have taken an interest in younger aquatic races such as the Hykraians, Qarians and the Atlanteans. They were responsible for uplifting the Hykraians and giving them the gift of interstellar travel. Their homeworld is a frozen planet with methane oceans similar to the Lakes of Titan.
