Ryn is a character from a TV-series Siren. She is portrayed by actress Eline Powell.
A mermaid convinced her sister, and they came to close to the surface to feed, which lead to the sister being captured by fishermen. The mermaid then came on land to find her sister, and was picked up by a man from the road. The man was kind and gave her clothes, but the siren only wanted to find her sister, and left. The mermaid came upon a house where a kid watched cartoons, and she heard a name Ryn, which she took as her own.
