Sŷlven is the language of the Sŷlvi people, living in the continent Sŷlven (in Sŷlven the name of a language is the same as that of the place from whence it came) of the planet Serâþ, or Kepler-296e to us. It developed in a biosphere for ten thousand years on it's way to Serâth from Earth (Arêþ to the Sŷlvi).
