Caspian, a marine biologist who is passionate about the ocean and all the living and non-living creatures in it. He has brown, shoulder length messy hair that's almost always tied up in a ponytail, contrasted by some stunning, blue eyes, shielded behind circular glasses. He's a nervous guy. He talks a lot, and rapidly, using some slang words sometimes. He's 24 years old and 6'1ft.

Queen of the Pearlspire, Nerissa. She's beautiful, sharing almost every feature with her son. White, silky, glowing hair that reaches her lower back, beautiful eyes with luscious eyelashes, pale skin and a lilac mermaid tail with a half-transparent end that shared the opalescent glow with the rest of the tail. She's kind and sweet, but when needed, she's intimidating, scary and serious. Her and her husband try to use slang words like the teenagers do, trying to seem cool.

Neifion, King of the Pearlspire. He seems intimidating because of his height and overall appearance but he's cheerful most of the time, also kind. He has tanned skin with many blue tattooes on it. He has purple, mid-back length hair and striking, golden eyes. He tries to use slang words like the teens to seem cool. His merman tail is a rich purple with that mesmerising opalescent glow only the royal family achieved on their tails.
