To put it simply, it is the story of Queen Elsa and Princess Anna meeting Jack the Freeze, and going to Hogwarts together to find Jack's lost memories and the origin of Elsa's magic. The full text is written in third person, and the time points are after "Ice 1" and before "Ice 2". It is divided into three parts, using HP as the stage and rewritten in conjunction with "Guardian Alliance".
Intention: Jelsa Jack Elsa yyds!
