A laughter always stood in a red lock. In an orange lock the strongest dwelt and adroit given. They arranged contests every day, and in them won. Tale-tellers lived in a yellow lock. They knew so much fairy-tales, that if it was begun to tell them, then did it whole year without breathing space. The best cooks of iridescent kingdom lived in a green lock. And what foods prepared there, you and not able to imagine. In a blue lock nothing was done, but it always was merrily there. Scientists and inventors lived in a blue lock.

This was the most enigmatic lock. Above an iridescent kingdom always, a rainbow stood in any weather. Certainly, magic. From iridescent magic all in the kingdom of жилос.
