Once upon a time ... there was a girl, named Nalo, who will be 8 years today. There's no real party though, because her mother recently died and you can't party without mommy.
Her father tries to cheer Nalo up by giving her a musicbox, with a glass snowglobe on top of it ... it was the favorite object of her mother Annah.
Once in her room Nalo discovers something strange, something is moving in the globe! She looks again and sees a girl that writes "Help" in the snow. What is this? With the help of instructions of the girl in the globe, Nalo gets into the box. After the snowy hill Nalo discovers a whole city ... Pandoria. It's full of strange characters and other monsters, but that are worries for later. Right now, Nalo need to help the girl as fast as possible.
