The USS Enterprise-D orbits Rekag-Seronia in 2369.
Rekag-Seronia (or Seronia) is an M-class world located within Federation space. Violent hostilities between two local factions, the Rekags and the Seronians, grew to such an acute level by 2369 that a local shipping route was threatened. The Federation despatched Ambassador Ves Alkar to mediate the dispute, in what would ultimately be his final mission before his death in the same year. (TNG: "Man of the People")
