Kelva was an inhabited planet in the Andromeda Galaxy. This was the homeworld for the Kelvans, a warp capable non-humanoid species. In the mid-20th century, Kelva was the capital of the Kelvan Empire.
According to an idea by Spock, a robot ship was apparently sent to Kelva along with the Federation proposal of peaceful relations and to offer some planets in the galaxy for the Kelvans to colonize. The Kelvan response would, however, take six hundred years to arrive.
