Rideis

They did not look so different, really, only a little more elongated where humans were pinched together, and the slight differences could mostly be explained as a variation of type. The tips of their ears were not so pointed as in humans’ popular art and could often be missed. The humans called them demons, or sometimes the Selks.
They called themselves the Rideis.
They had been a great people once, and they still considered themselves such—but secretly, Kayvin wondered if their days of greatest glory were gone forever. They no longer made active war on each border, fighting both scales and leather, and while Kayvin practiced daily his forms and magics, he spent more hours with his music. His father Gromgest had led hordes into battle when he was young, long before he had sired Kayvin, but now he passed his days and nights with his sera qadra, achieving conquests of another kind.

From the perspective of [country], the Rideis live on the far (eastern) side of the Gornfar Mountains. They say something else lives further east, something which they once allied with humans to fight, but this is not supported by [country] histories.
