Winter
Sarralyn thrived in winter. Her family couldn't quite understand it, but Sarralyn would love to experiment with her transformations in this season – one moment she was a furry white fox, the next she was a large bear.
Winter seemed to her the best season of all – not just because of the snow, which she loved immensely – but because of how magical the world appeared. People seemed to look at the world differently in winter, and they seemed softer, somehow. Sarralyn liked that.
One winter, she had turned into a great black wolf, and had charged off, armed with childish energy and ready to explore. She had gotten lost, and only after what seemed like days did her parents find her and take her home. She had endured a long lecture about safety, but that didn't stop her unconditional love of the season of winter.
Spring
Spring was the season when everything began to come to life, and Daine loved it for that. She loved the way the flowers would begin to spring up out of the ground, always so fragile yet entirely beautiful. Compared to spring, all of the other seasons seemed dull and uninteresting.
Everyone, she thought, loved spring. After all, who couldn't adore the way the snow began to melt, slowly but surely, the sun began to shine more, and warmth began to seep back into Tortall.
It baffled her that the other members of her family preferred other seasons to spring. She couldn't understand it, no matter how hard she tried.
Summer
To Rikash, summer was the season where the sun came down and lit everything on fire. It was a season that stank to him of destruction, and yet he loved the warmth anyway.
Summer was the season when he liked to do things. He wasn't lazy during winter, spring, and fall, but he wasn't as motivated as he was in summer. In summer he felt like he could do anything, be it something considered entirely possible or something considered completely impossible.
In summer, people seemed to set down their weapons and relax. For someone that had no skill with a sword, javelin, or other weapon of any kind, that made Rikash feel more at home in a country where warriors were the most respected people of all, and less of an outcast.
Fall
Watching the leaves change color and slowly, gently drift down from the branches that held them was of immense pleasure to Numair. He would sometimes watch a leaf descend to the ground from his study, distracted momentarily from his work.
When he was a boy in Carthak, he had once been asked what his favorite season was. He had then observed for an entire year the good and the bad each season had to offer. Fall had come out on top in Carthak. When he reached Tortall, he did the same. This was partly because it was something he wanted to do to adjust to his new homeland, and partly because it was something that reminded him of when he had arrived in Carthak (a place he missed, however much he denied it). Again, he judged that fall was the best season.
