A world (pronounced "KEFF-kuh") where Verad's lover Mareel grew up; it is unspecified whether her humanoid species is native to the planet. She speaks of growing up on its "rough streets" and working at an accommodation house where she met Verad, but it may not be as bad as all that; the United Federation of Planets had a consulate there, where he worked.
