She was the Summer Princess, fair and true. He was the Winter Prince, cold and harsh. But then the seelie and unseelie courts have always been opposites in every way. The Summer folk liked dancing and kissing. The Winter court liked war and rules. They did not mix as they had nothing in common. Neither did they fight each other as the Winter Fairies would have slaughtered the peacelovers at with one strike.
But every spring and fall they met and gave over the spire of Season. The Summer court was in full bloom when the Winter Court rode in. With unfeeling eyes they looked down at the bright colors and the laughter and frolicking going on. And Summer rolled their eyes at the strict Winter court who all had a rod up their asses.
The Ceremony was long and dull, even to the Winter Court. The priests went on and on. And as always they spoke of the one to come. The Child of Winter and Summer who would rule over both courts and change everything. The child who would take back the Dark Lands from the Sidhe who stole them long ago. It was then the young Summer princess looked over and caught the eye of the Winter prince. She smiled as her people always did and he, for a moment he looked beyond the silliness of her kind and saw her beauty and strength.
During the dinner Summer made her escape to the hills she loved and danced in the pale moonlight. Winter defied the rules and went to explore. There he saw her, dancing and laughing and his cold heart jumped for a moment. He went up to her and looked into her eyes as she stopped and fell into his arms with a laugh. She had never had a Winter Man to her bed and took the chance. For one who liked control he showed it well and it was nothing like the Boys of Summer. Even if it did feel a bit unfeeling he took her where she wanted to go. And without having uttered a word they lay there while the moon looked down upon them. Winter felt a spark starting to grow within her and pondered the consequences. A child of winter and summer. Uniting them both? He knew well that Winter wanted the Dark Lands back, and the Fields of Glory. But now, not now. So he smiled and she looked up with surprise and smiled too. A smile that slowly faded as he took the dagger and plunged it into her belly. Then he left her there, bleeding and alone. That is what he got for defying the rules.
