Mermista is the princess of Salineas and a member of the Princess Alliance in The Rebellion. Sarcastic and blunt, Mermista keeps a stony face and a cool head most of the time. That doesn't mean she's emotionless; she just finds it hard to express her true feelings. She's stoic and has no problem speaking her mind, but often shies away from verbally expressing her feelings (particularly about Sea Hawk). Mermista does not back away from hard or difficult work. She can be very dramatic when she gets into the role.
