Chodak

The Chodak are an ancient species of soft jelled creatures that resembled mollusks. They wore an artificial shell that presumably contained some of hover device that allowed them to move and to communicate.

Their homeworld was the planet Allanor which was located in what is now the Romulan Neutral Zone while a majority of their territory has been taken by the Romulan Star Empire. However, certain colonies such as Horst III and Frigis were within Federation territory.

The Chodak founded a mighty and powerful empire that existed four thousand years before the birth of the Federation. This empire collapsed when their source of power; the Unity device was sabotaged by rebels and caused the government to lose power eventually. The fate of this species is not known, however, automated ships were known to prowl the spaceways; destroying any ship that they encountered.
