H'atoria (planet)

H'atoria is a small Klingon colony near the border with the Federation.

The world had very few landmasses, and was mostly covered in oceans. It also featured a native amphibious species called the Selsseress.

In early 2381, it was one of the many worlds devastated by the Borg attack, leaving virtually nothing behind, only a few surviving Selsseress. About 3 months later, the now-abandoned world is conquered by the Kinshaya, as part of the new offencive against the Klingon Empire.

Alternate Future
(In an unknown, alternate future timeframe, Worf was governor of H'atoria in 2395. (TNG: "All Good Things..."))
