Regina Mills X FemOC

Abandoned as a newborn by a woman she'd never known, Adirra Evanna and her twin brother were rescued by their fairy godmother, Tigerlily, who entrusted them to their Father Malcolm. Hesitant about his ability to raise the children without their mother, Malcolm took them in. Although he made sure they had a roof over their heads, his blind hatred for his son, married with substance abuse and emotional neglect, only fed the growing resentment within Adirra's heart.

A resentment that with every injustice her father inflicted, clawed through her like a scream she never dared to voice and eventually began to manifest as something sharper, something with more spite. Magic. Dark Magic.

Growing up with a father who feared her but also knew exactly how to hurt her and would, given the opportunity, affected Adirra more than she'd like to admit. After finally escaping a man who resembled the devil, Adirra resided in a secluded cabin, deep in the enchanted forest. Her life of isolation was integrated by the only two people Adirra had ever let get close enough to stay, Tigerlily and Clare.

However, this peace was quickly fleeting compared to the next two and a half centuries she was forced to spend with the man that abandoned her and her brother as children. Exposed to the harsh reality of a world that tried to control her, Adirra thought she'd be subjected to a life of solitude for eternity. That was until a soft, brown-haired boy, firm in his beliefs and adamant that his family would rescue him, arrived on the island. Luckily for Adirra, they did, but of course, nothing comes without a price.
