Abigail McKenzie

Origin
Abigail was born in the lower lands of the Cloud Kingdom and was accepted into the Assassin’s Guild at age ten. Her first job as an assassin was to assassinate the Applegate household, which she succeeded. When she turned fourteen, the assassins broke into the castle to kill the king, and most assassins were defeated. The king had been murdered by Abigail's sister, who was defeated by Prince Albert. By the end of this battle, Abigail was the only assassin left, but couldn’t bring herself to kill the prince. The prince had mercy on her and made her the personal guard of the royal family, where she had served ever since before meeting and recruited by Ilya.
