The first of 3 versions of Emerald's refsheet, this is her before becoming a Bête Noire, the second will be for her powered down Bête Noire form (ears are Celeste), and the 3rd will be for her powered up form (whole head is Celeste). Emerald is an Overseer, most Overseers don't have a specific soul Trait, however, Emerald had an overwhelming ammount of the Kindness Trait, but was incapable of showing her soul, she used to be a happy go lucky person who thought everyone was her friend, when in reality, everyone she met was just taking advantage of her Kindness. Once she had realized this, Emerald had done some research to determine the best way she could get revenge, she found the Bête Noire spell, a spell that requires the body of another to help keep oneself alive after inverting their Trait. Emerald had used another Overseer's body for the spell, one with a hidden Trait of Justice, causing her soul to turn Celeste in color, and making her the first Wrath Bête Noire. If any other Wrath Bête Noire's come into existance after her, due to her being the first, their souls will always become Celeste, and this color is locked for all forms of Bête Noire. Stay tuned tomorrow for V2! Also, at some point soon, I will be posting a journal with info about every Trait and what me and my friend have deduced each Dual-Trait's power is.
