Forty-one years before the special, an evil sorceress from the Northern Islands named Shuriki attacked the Kingdom of Avalor and killed King Raul and Queen Lucia. Alacazar cast a spell to protect the remaining members of the Royal Family by placing them inside an Enchanted Painting. To buy Alacazar time, Crown Princess Elena of Avalor faced Shuriki on her own. Shuriki tried to strike Elena down, but the Amulet of Avalor saved her life at the cost of her freedom by pulling her into it. Alacazar found the Amulet and spirited it away while Avalor fell under Shuriki's control. Knowing Elena was the only one who could defeat Shuriki, Alacazar set out to find a way to free her. He summoned his spirt guide Zuzo who told him he had to find a special Princess who was chosen by the Amulet to get Elena out. He travelled all over the world to find this Princess and tested each Princess from Princess Charlotte of Isleworth to Grand Mum and then her daughter Tilly. While each managed to unlock the Amulet's powers and break its curses, none of them had what it took to free Elena. When he grew too old to continue, he preserved himself by turning himself into a magical book that became part of the Secret Library of Enchancia's collection.
Forty-one years after Elena's imprisonment, Princess Sofia of Enchancia is finally prepared to release Elena from the Amulet of Avalor. He reveals the story to her and she sets out to free Elena. Upon doing so, the two Princesses then defeat Shuriki and free Avalor. Upon Sofia's return, Alacazar congraulates her and vanishes. His fate remains unknown.
