The "kykr" are the dominant civilisation of the world, encompassing three sapient species: The Illim, the Vindral and the Kuna. They rule over the continent of Arjin in a diverse collection of cultures and nations.
The word "kykr" is derived from ancient Ósleiðr and means "kin" or "friend". It is used similar to how we use "human" or "humanity". In a world without humans and with a multitude of species living together, the kykr found a way to refer to themselves as a unity. That word was "Kykr".
