The Asrai can be described as an aquatic fairy, and can resemble the Selkie. In appearance, it is said that the asrai can look like a beautiful young maiden, sometimes as youthful as children. In actuality, they can live to be hundreds of years old. Asrai's can appear to have webbed feet or hands.

It is believed that if an Asrai is caught or even touches sunlight they will die and melt into a pool of water. In some Lore their touch leaves your skin (where they made contact) forever cool; never able to be as heated as the rest of your body.
