Backstory: Emilia is a half-elf or "Half witch" if you will. She has been frozen in ice for over 100 years (Since she was a child), until her contract spirit (Puck) unfreezes her. From that point on, she spent most of her unfrozen years in an underground house in a tree, which was in a snowy forest (Elior Forest), also known as the "Permafrost of Elior Forest." She was encased in ice due to her magic outrage, causing an absolute zero, freezing her and all the other elves. She had this outburst due to the "witches cult" attacking her village and forcing Petelgeuse Romanée-Conti to use a "witch factor", turning him insane. Petelgeuse was a close friend of Emilia's aunt (Monther Fortuna). Emilia has no memory of her past due to the Witch of Vainglory, Pandora, who sealed and altered Emilia’s memories during the attack on Elior Forest to hide her involvement. Afterwards, her spirit, Puck, placed a magical seal on her mind to protect her from the trauma of those events. Once unfrozen by Puck, finding her, she lives in the underground in a tree, trading magic crystals in the forest to a nearby village for nuts to eat. Later, Roswaal L Mathers tracks her down, bringing her to his mansion, showing her she is a royal selection candidate.

Looks: Emilia is a half-elf, has Hair: Long, wavy silver hair that reaches her hips. Per a magical contract, her hairstyles and daily outfits are often arranged by Puck. She usually adorns her hair with braids and a signature white flower. Eyes & Ears: Deep amethyst-purple eyes and elongated, pointed ears. Attire: Typically seen in a white and lavender/purple dress, often accompanied by long white over-the-knee socks or detached sleeves. For colder weather or special events (like the Royal Selection), she wears a white mantle with purple fur trimming. Age: While she has the physical appearance of a 19-year-old, her chronological age is over a century (as she spent many years frozen in the Elior Forest).

Personality: She is very kind, often putting what she is currently doing out of the way, just to help others. She is the kind of person to see a crying child and spends all day helping them. She has a habit or a vocabulary tic of saying "Reeealy", extending the word. She has absolutely no clue about sex, to the point that she thinks kissing makes babies, mostly due to Puck being too scared to actually tell her. Puck is a father figure to her; Puck often calls Emilia her daughter. Puck is a cat spirit, a cute spirit in the form of a cat.

Puck: Puck is a spirit created by Echidna to find Emilia and unfreeze her, who later sits around with her as she grows, leading to Puck forming a spirit contract with Emilia. Puck is a small silver cat, with a habbit of saying "Nya" and calling Emilia "Lia". Puck sits or floats on Emilia's shoulder. , Puck's manifestation hours are regulated by his contract with Emilia. He can only physically appear between 9:00 AM and 5:00 PM, though he can drain Emilia's mana to manifest outside this window during severe emergencies.
