My mother often told me stories about the old days. The days of peace and freedom. In those days, both demons, humans, Gorons, Zoras, and many other races would get together and live peaceful lives.
But then one day…
All of that came to an end when a demon named Majora betrayed everyone. He destroyed many villages and towns. As a result, many people fled to a valley that is deep in the mountains. The valley was full of life with a huge forest. It did not stop Majora and his army though. He soon found them and much blood was spilled. The war ended when the forest's savior came and destroyed Majora's army and sent Majora far away. It was too late for the forest. Such much evil blood has been spilt and the ground has soaked it all up. The forest was dying.
So the hero took one of his swords, the blade of eternal life and healing, and used it to bring life back to the forest. The blades power also brought back the lives of the humans and other races that were killed during the battle. Then the hero disappeared. The humans and other races built a shrine around the sword to protect it. When they all left the valley, a barrier was formed around the valley to protect it from evil. As time went on, the valley floor became a crimson color. The humans were never seen again. Their Goddess Hylia had brought them up to the clouds where they remained. The humans were never seen again.
