Selkies

Selkies are an aquatic (amphibian?) species that inhabit the Fyr Marsh. They have dark, pupil-less eyes, and dark skin.
They have also been seen in the river that runs through the Hollylin Woods and in the aquatic passage of The Ruined Temple of Tymur. There is a Selkie settlement in a blue hole off the coast of Obica south of Twin Fingers.
