Headscratchers / The Snow Queen

How are you supposed to make windows and glasses out of a mirror?
  • They're pieces of a Magic Mirror.
    • They're also small fragments.
      • The mirror was made by the Devil himself, and required several lesser demons to carry it. It's not hard to believe the thing was huge. Now, who would be desperate enough to make a window out of a random piece of broken glass on the ground? Without noticing its magic first?
    • Someone who was very poor, who wanted to try and keep the cold out of their house, and didn't really know much about magic mirrors, none of which would be exactly uncommon in nineteenth century Scandinavia.
