Everallin is a Melusine, which is a short, cute humanoid creature that are reminiscent of sea slugs. She has purple eyes and brown hair. Like all Melusines, Everallin also has a pair of antennas that help her sense the ocean's movements as well as a tail. She has a short snout, and her skin is a combination of bright white and dark black in patterns, like a sea slug. She's a member of the Gardes in charge of keeping Fontaine's Romaritime Harbor safe.
