The forest people were going by their usual day to day lives until fateful one day, around a hundred years ago, the barrier surrounding their lands disappeared, and they started to get disturbed by people holding and wearing metals as their weapon and protection. For the time, in a hundred years, they found out that they had neighbors living in stone houses.
At first, the forest people wanted to trade with them but as more interactions occurred, the greediness of humans happened and soon, the hundreds of tribes had found themselves with one foot beneath the grave due to the overpowering might of the people who lived on stones. The tribes then united under the leadership of a woman, which some said was a mythical creature, until they managed to drive back the invader of their lands.
