Castle Swimmer

Castle Swimmer is a featured webtoon created by Wendy Lian Martin.

Synopsis
What happens when your entire life is ruled by a prophecy – your future foretold by people you’ve never met, who died long before you were born. Such is the story of two young sea creatures. One believed to be a guiding light for his people, a Beacon who will lead them to a bright, prosperous future. The other is a teenage prince for who’s destiny is to KILL the Beacon so that HIS own people might thrive. When both reject the course set for them, it leads to a raucous adventure as big and unpredictable as the ocean itself – and a romance that nobody could have predicted.
