Ermine is quite a friendly personality, always cheerful and always happy to assist unconditionally, which is rare among the fey. She might enjoy a little prank here and there, but it is never something that would be harmful to anyone.
Being a Nereid he feels a special connection with Caislean Ridire and its residents, but on occasion she travels with Sands to help him and train with him, training that which she can then share with the rest of the Moths once she returns. She is the resident grandmaster-at-arms, and can use just about any weapon, though her particular choice is a long slender blade made of solid silver handcrafted by Luna. This weapon is a fencing foil, which functions like a rapier. Thanks to specially crafted grooves in the blade she can transfer a little bit of the poisonous water she creates through the blade and into the wounds she deals. However, her deeply ingrained appreciation for all life burned into her by Sands manifests in said poison being a mere paralytic rather than something deadly.
- Luna she appreciates and respects, and he wishes she would be more open to him and sometimes travel with him and Sands
- Imperio she tries to teach the appreciation for life that she herself was taught, and has deep respect for the efforts he put in fighting those urges
- Rosy she considers a great ally and a friend, in free time often they spend time together learning forgotten secrets of the Caislean Ridire
