NightDream (?)

prehistory..
In a kingdom far, far away, there lived a king and queen. Their state was flourishing, and relations with other countries were excellent. Then, one fine day, the king and queen had an heir – Nightmare, a stern and intelligent boy who seemed a perfect replacement for his father and mother. Ten years later, a second son was born – Dream. Golden hair, golden eyes, freckles… Unlike Nightmare, who took after his father, he took after his mother (which is why there were such striking differences in the two brothers' appearances). Dream was active and creative – he loved to draw and was always organizing something. But in the castle, they were making a prince out of him, not an artist. They forbade him from drawing, and they wanted to lock him up, but… It was not to be. During one of the balls, when Dream was about seven years old, he ran away. They searched for him, but to no avail. Everyone was grieving, because they thought he was dead, even though they never found his things.

..ten years have passed..

Resurrection. Nightmare and his retinue walked the streets of their kingdom, observing the lives of the peasants. Now Nightmare was already king – a grown, stately man, but… Still without a bride, unfortunately. His deep emerald eyes glided over the faces of his subordinates, thinking of his own. He hardly thought about his brother, though the pain for his lost brother remained in his heart, occasionally tormenting him at night.

Nightmare, like the castle's inhabitants, is almost obsessed with returning Dream (if he's alive) to the palace, even if he's against it. The villagers, on the other hand, love him dearly and often help him hide, because Dream is essentially a sun who has done good deeds without retribution.
