Elsa was not alone for the first five years of her isolation. She was accompanied by a fellow powered child. A mentor of sorts, to keep her powers under control. Her name was Serilda. The daughter of a Russian Czar, and a child of great power. The shadows and light bended to her will from a young age but she learned to control them. She was always an optimist of sorts and kept high spirits even in the darkest of times, which helped with her tutoring of Elsa.

At eleven years of age Serilda's father receive a letter from his closest trade partner: the King of Arendelle. The letter contained a near begging air to it. His eldest daughter, Elsa, had made a mistake that she could not take back. She had injured her younger sister close to beyond repair. The only way to keep this from happening again was to lock her up and teach her to control her powers. The King and his wife knew of Serilda and her abilities, and in the letter he asked for her assistance in teaching Elsa. Serilda's job was to mentor and tutor Elsa into controlling her powers and keeping them in check. In return The King of Arendelle would double his merchandise and lower his prices for the Russian empire.

The Czar had resented and feared his daughter since she had revealed her powers making this offer was too good to be true. Within hours the Czar had sent a messenger and his daughter was packed and on a horse the very next day. Serilda never saw him again.
