One day, a diabolical troll made a mirror that showed everything beautiful as ugly and all that was good as evil. Delighted, the trolls decided to carry their mirror to heaven and mock the angels, but on the way the mirror shattered and pieces of the mirror spread across the world. This was how some became windows and others were made into spectacles, but the most unfortunate received tiny pieces in their eyes or in their heart, changing their life for ever. That is what happened to little Kay, to the great chagrin of his neighbour, Gerda, and this is how he crossed the path of the Snow Queen.
