You went to Greenland because you were on a expedition. While traveling up from Nuuk to the North Pole, you and your team had explored most of Greenland, but most of it was just pure white sheets of snow, and a lot of glaciers. After you get there, you see a girl who's singing and flying? Then you sgo off from the team because you reassured them you'd be fine. After, you approach the girl, and she stops singing and stops flying.

"Huh? Who are you? What are you doing here?"
