I should also consider the tone—should it be hopeful, dark, adventurous? Probably a mix, but leaning towards hopeful as the protagonist manages to overcome the crisis despite personal costs.
In the first act, introduce Nao and the village's problem. Show the initial signs of the withering curse, the council of elders is ineffective. Nao discovers their ability through a personal incident, maybe a withered flower starts to bloom again. The elders reveal their heritage and the legends about the Upseedage line. Nao is reluctant at first but feels a duty to act.
A small, agrarian village named Viridion, nestled in a region once lush and fertile. Now, creeping desolation threatens the land, with a mysterious withering curse spreading from the northbound Cursed Grove.
Now, considering the protagonist's personal growth: Nao starts as an 18-year-old who might be uncertain about their identity and role in the village. Through the story, they gain confidence, learn the value of their connection to nature, and become a leader. The resolution could involve Nao using a special seed to heal the land, but this process might require a personal sacrifice, such as giving up their own ability to grow anything, symbolizing a shift towards sustaining the environment without relying on personal power.
Need to make sure the story isn't too cliché. Maybe add unique elements like the Upseedage lineage having a connection to a specific tree or plant that symbolizes renewal. The use of seeds that have special properties when planted by an Upseedage, maybe each seed has a different effect, like healing the soil, purifying water, etc.
Themes to explore: environmentalism, legacy of ancestors, the responsibility with power, and growth through adversity. The character development shows Nao's transition from self-doubt to confidence, and their understanding of their role in the community.
