Feathers

Once, Mother Nature and her children(the animals and plants) lived without fear of anything happening to them, when 2 humans come to their island, seeking food, water, and shelter.

Mother Nature pitys the new-comers and sustains their needs, and quick-growing curiosity(as such questions), and sends them on their way.

Soon, the beings, now identified as humans, come back with a few slightly severe injuries, and 2 more of their species, saying how they were outcasted because of their preferences.

Mother Nature is infuriated by this, and welcomes them with open arms, not aware of the dangers that "harboring outcasts" would hold.

When the rest of their species come to their island, they demand the outcasts to be punished to death, and when Mother Nature and her children refuse, it sparks an unwanted war between the humans and animals.

During the war, Mother Nature becomes mates with one of the humans, and has a child. A boy, to be specific.

That boy is a feathered human boy , one who is destined to stop the war of ghe Animals and Humans.

But, as the boy is told this by his father during his mother's last few days alive(due to an unknown illness), he doesn't accept his destiny and runs away, and hides away in the Misty Mountains, not to be seen again, until a young boy, who was currently running away from his village, climbs the misty mountains and through a cave, to find the boy....asleep on the ground.

Once the run-away finally wakes him up, he tells the boy of his problem, and the feathered boy agrees to help the boy with running away, when soon, his destiny catches up with him, and he is put in a dilemma of whether he should ignore the prophecy, or if he should tell his new friend about his true purpose, and end the war.
