Bio: Serena isn't like most mermaids, she's one of more rare breeds. 

She is a mermaid who can see into future much like an oracle, or a mystic. Her visions occur as dreams, including both merpeople and humans, since they are to some extent connected. Her people saw it as her obsessing  over the humans, and eventually she was cast out. 

Serena lives off in a secluded cave, away from most forms of life. She does often venture to the surface if she had a vision of sort, just to keep the ocean safe. However, when she dreams of meeting a human personally, she doesn't know what to do with herself.
