Kiva
this planet was home to a race of beings known only as the Kivans. Borborygmus Gog and Mammon Hoole set up the first laboratory dedicated to Project Starscream on the planet, after receiving funding from Emperor Palpatine and the Imperial Science Division, where they experimented with the power of life and death. Although Hoole advised the Emperor that the project would utterly destroy all life on Kiva, it made little difference. The Kivans were wiped out when Borborygmus Gog ordered the continuation of Project Starscream, and the experiment itself was horribly wrong, killed everything on Kiva, including the Kivans. The planet itself was left a barren, rocky wasteland, and was haunted by the wraiths of the Kivans until Gog was killed by them shortly after the Battle of Yavin.
