Kurtiss Branta is the Sand Dragon spy for the king and queen of Iceberg Kingdom, a cold, tundra-like area of land much like the North Pole. The citizens know him as the tough, never-back-down, trust-no-one type of dragon. Which could very well be why he's the royal spy. He's stopped many terrorists, prevented wars, and kept the kingdom running smoothly with no fighting or misbehaving in any violent way. So when he successfully captured a group of three Fire Dragon terrorists, he took them to the law with pride and never gave them any thought of compassion. But little did he know that this year, his heart was going to change more than he ever thought possible.

You see, Wintfes, the annual winter festival to celebrate the Coldest of Days, was never his thing. It made no sense to him why the Ice Dragons chose to celebrate the freezing weather, give out presents, spread unconditional love, and decorate a large pine tree full of colorful lights. Why should he care about it when he could just continue his life and scoff it away completely?

But after he fights with a young Ice Dragon named Holly, the queen punishes him by assigning him a present giving task. He gives the festival more thought and apologizes to Holly for his outlandish behaviour. But an evil arises as the three terrorists escape. Ramrage, the leader of the group, skillfully causes him to betray the kingdom entirely and almost ruin Wintfes for all of Iceberg Kingdom. Will Kurtiss be able to stop the terrorists, change his heart, and become a gentle present-giver all before Wintfes is over? Or will his new adventure put him through the test, and prove that his kind heart may not exist at all?
