Eveline Edelstein is a character from “Mermaid Princess Amelia and the Destiny’s Theater” by Maxine Foti.
Identity and Role
Eveline Edelstein is the daughter of Mrs. Edelstein, one of the royal advisors to the Third Count of Nerland, and she serves as Amelia’s first lady-in-waiting and translator during Amelia’s stay in Rosenbach. She was also a candidate to become Amelia’s personal knight, but she lost that opportunity after an anonymous letter reached the Third Count. She wonders who wrote it and what it said. Beyond her official duties, Eveline wants to become an advisor herself, not an actress, because she believes many things in her country need to change. She helps her mother as much as she can and is described as her mother’s right hand. Angelisea says Eveline’s parents are incredibly supportive and loving, unlike her own.
Appearance
She has long, wavy silver hair and piercing grey eyes, and she radiates confidence. Her everyday style is bold: she wears a black choker and a matching black dress with a jagged hem, which made Amelia immediately suspect she might be a witch, though the text never confirms whether she actually is one. At the welcome ball, she wears a dress printed with the entire city, styles her silver hair in an elegant updo, and wears moon-shaped earrings. During the battle, she wears silver armor, and as the Black Knight, she wears the Black Knight’s helmet and armor.
Personality and Demeanor
Eveline is consistently described as stern, cold, detached, curt, serious, and pragmatic. She is not talkative, and her silence often makes her seem distant. She is efficient, formal, and dutiful, resolute and brave under pressure, and protective of Amelia even when she scolds her. She is deeply affected by Wilhelm’s injuries and fights with fierce determination afterward. She has little patience for what she sees as self-centered behavior, and she tells Amelia she wants to be her true self, not molded into someone else’s image. She gave up her childhood dream of acting, saying she cannot waste time “reciting lines and making people laugh while others are shedding tears nearby.” She is interested in politics and reform and wants to become an advisor.
Skills and Combat
She has over six years of fencing experience and usually trains with Wilhelm in the mornings. She is skilled enough to be chosen as a replacement Black Knight, capable of fighting in full armor, wielding a sword, and defeating a dangerous enemy knight in single combat. She is also a translator, speaking the local language and Ocean Language well enough to translate for Amelia and read official documents aloud. She understands political and environmental issues, including the dead zones caused by algae growth and oxygen depletion in the Baltic region. She knows about the upcoming summit and the need to include a Southern Baltic representative, and she knows about Magisk Hav and spell rings, at least through her mother’s knowledge.
The Black Knight Secret
Eveline is one of the two Black Knights of Nerland. She reveals this to Amelia after Wilhelm is gravely wounded: “Wilhelm and I are both the Black Knight, appointed by your grandfather, the third count.” She explains that if the Black Knight dies in battle, a replacement is needed, and Wilhelm selected her to assume the role. This is why she and Wilhelm always train together. When Wilhelm is injured in the duel against the enemy Black Knight, Eveline dons the armor and fights in his place. She fights with fury over Wilhelm’s injuries, defeats the enemy knight, tears off his helmet, slaps his cheek, and declares: “The enemy is defeated!” Her mermaid voice carries so much power that it seems to shake the arena.
Key Actions and Events
Among her key actions and events: she is introduced as Amelia’s translator and lady-in-waiting; she is present at the welcome ball, where she quarrels with Angelisea; she informs Amelia about the dead zones and the upcoming summit; she shows Amelia the Second Countess’s Summer Room; she discusses the Third Count’s missing emerald ring and suggests it could be a spell ring from Magisk Hav; she suggests Wilhelm might know something about the ring; she reads documents aloud during Xylemander’s formal arrival; she warns Amelia of the bombardment; she learns from Wilhelm that the Third Count is missing; she insists Amelia remain in the palace, then leaves to handle the emergency; she fights in silver armor during the battle; she searches the ruins and rescues Angelisea; she conceals Angelisea in a stone hut and treats her with curtain fabric and whale grease; she takes Angelisea to the hospital; she joins Amelia and the generals at their tents; she dons the Black Knight armor after Wilhelm is wounded; she defeats the enemy Black Knight; she accompanies Amelia as translator during the post-battle confrontation with Xylemander; and she explains the fig sign when Opa uses it.
Relationship with Amelia
As Amelia’s first lady-in-waiting and translator, Eveline initially seems cold and detached, but she is consistently protective of Amelia. She warns Amelia during the bombardment and insists she stay in the palace because she is the only ruler available with the Third Count missing. She scolds Amelia when Amelia sneaks out, but then stays with her and acts as her knight. She reads official documents aloud for Amelia and translates during the confrontation with Prince Xylemander. She explains the medieval “fig sign” to Amelia. She was offered the role of Amelia’s knight but lost it because of an anonymous letter, and she suspects her position was not considered significant because Amelia was only visiting temporarily.
Relationship with Angelisea
Eveline was once best friends with Angelisea. They shared a love of theater and rehearsed together. Angelisea kept pursuing acting, but Eveline lost faith in herself and stopped trying. Angelisea says Eveline was always too busy serving as her mother’s right hand and kept putting off a return to acting. Eveline eventually ended the friendship. She says Angelisea believes the world revolves around her and her theater, and that Angelisea kept trying to mold her into someone she was not. Eveline says she is “completely done” with that friendship and just wants to be her true self. At the welcome ball, they have a strained conversation. Angelisea looks upset; Eveline stands with crossed arms and a defiant expression.
Relationship with Wilhelm
Wilhelm and Eveline are fellow Black Knights and training partners, bound together by a secret appointment from the Third Count. She is deeply concerned for him when he is wounded and says firmly, “He will survive.” She removes his helmet, rinses the blood from it, puts it on, and takes his place in the duel, fighting with a fury that is awe-inspiring.
Her exact feelings for Wilhelm are not explicitly stated in the text, and she never confesses or directly expresses romantic interest. What is clear is that she is emotionally invested in his survival, furious at his injury, and driven to avenge him.
