Drek'la

The Drek'la are a spacefaring species.

In 2373, the Drek'la worked with renegade Cardassians to conquer the Tiffnaki homeworld, a planet rich in latinum. 

Benjamin Sisko and the crew of the USS Defiant (NX-74205) (I) were later able to help the Tiffnaki force the Drek'la and the Cardassians off the Tiffnaki planet.
