Fafnir is a former Kzin colony covered almost entirely in water. One long, rocky and barren continent. Annexed from the Kzin by Humans after the Sixth Man-Kzin War, in 2618.

When under Kzinti control it was called Shasht, a Kzin word meaning "burrowing murder." It was captured by humans during the Man-Kzin Wars. In fact after the Sixth Man-Kzin War, in 2618. Humans and Kzinti now cohabitate. The humans prefer to live on the coral islands while the Kzinti prefer the single large continent which they continue to call Shasht.
