Frozen Imbalance

In a fantasy world, people have been divided into biomes and kingdoms. They have lived in peace for hundreds of years, and all is well.
Queen Lily of the Jungle Kingdom kept the peace in her kingdom for years, and kept them out of wars for years, but when a cold wind blows in, she is forced to throw away her peaceful attitude and protect her kingdom...
Or else she might lose all she's worked for.
