Snow is here
Once upon a time there was a young nature goddess who kept the weather and seasons in check. She was great at her job. She helps the people grow crops, stop famine and turn barren areas of the world green. With her powers over nature and its seasons she was able to do so much and she wanted to spread her influence to help more people so when she had a daughter she wanted the best for her. She wanted her daughter to grow up and help her people same as her mother but the baby fell very ill and all the power in the world couldn't help the child. In the end, the child passed away. This caused the goddess to fall into a deep depression whilst she was away from her duties. The weather changed and became harsh causing winter and snow. After months of grief she decided to come back to the world but every year around the anniversary of her child's death she goes back to her depressed state causing winter every year.
