It started out as an average night for Sandy. The children of Corona slept soundly. Sandy made sure to give the princess dreams of adventure in hope that one day she might reunite with her parents, before going on to the kingdom of Arendelle. The little reindeer boy had a troll singing a lullaby to him. Good, Sandy thought. The boy needed a home and the trolls would help him recover from the loss of his parents. Sandy sent a darker dream to him in hopes that the comfort from trolls would help them grow closer. It was only when Sandy got to the princesses that he noticed amiss.
There was magic in Anna's head that was not his and little Elsa wasn't even asleep. She sat in her bed quivering. Her frozen arms crossed. Her eyes were shut like she was trying to shake off a bad dream. Sandy frowned. Something happened to them and it was clearly not good. He sent Elsa the sweetest dreams anyone could imagine. She tried to fight them off, but Sandy persisted until she fell asleep.
Then he did something against his morals. Sandy sent a stream of clear sparkling sand into Elsa's head and searched for the memories that caused her fright. As Sandy watched Anna fall and Elsa's panic, he knew something must be done to ease Elsa's fear of her powers. So, Sandy got involved.
It took him awhile to figure out what he could do. It was the trip to the Vikings that inspired him. This particular village had more problems than most. Little did the residences know that one problem was because to the first problem, dragons. The snow glistened on the roofs, while fire lit up the sky. Sandy was used to the snow not melting despite the dragon's fire. So were the Vikings. They never quested how the snow and ice was cold enough to not melt in such heat, but the answer was waving to Sandy.
Years ago, Jack Frost became enraptured by the dragons. He spent half of his time in this village just to catch sight of them. Sandy always thought Jack kept coming back because the dragons were always more sensitive about spirits and acknowledged Jack by glaring at sudden snow on their wings.
Jack. Jack was the answer.
The next night, Sandy visited Arendelle's castle with a smile. He was worried when he found that Elsa had been moved to a different room while Anna stayed in the old one, but he hoped the dreams he gave her would be the companion she lost. More than anything Elsa needed to see that her powers weren't to be feared and who better to show her the wonders of snow than Jack Frost. Dreams of Jack causing snowball fights, sledding, and laughing would be the staple of Elsa's dreams until she stopped fearing herself. Because, what could possibly make her forget fear if not fun?
And if she started to believe in Jack Frost, well, they could both use a companion.
The boy who couldn't be seen and the girl who couldn't show herself. Two people who would do anything to protect those they love. Both of ice and snow. There weren't two people who needed each other more.
