History: Much like summer and winter power holders worked together, spring and autumn power holders did as well. Spring ones used to be dedicated healers, who also purified toxins and curses out of the nature, and grew new plant life, while autumn ones helped by restoring the earth and protecting the spring power holders on their journeys. These traditions have long since been forgotten, even if each power holder works indepently to aid the world to their best ability.

Science: It's scientifically possible to combine a human with anything else found from Ellipsa. My research, now wrongfully shut down, shows that anyone could become a better version of themselves just by a few experiments. We could survive without seasonal powers! Become enhanced humans! But the leaders of the world shun my scientific progress and refuse to let me continue my tests. If they won't support me, I will do it without their help. They will be sorry when they realize what they missed out on.
