The Last Guardian

Rain a little girl was out with her friends playing in a field near her home village when she spotted a small round copper disk lay half buried in the dirt. The disk as she got close to it started to glow a mysterious green that got brighter and brighter. When she reached down to touch it everything went black. When she awoke she was in a musty half lit cave with a big steel chain leading to a big mystical creature, long thought forgotten lay still in front of her. The two must lean to trust one and other to reach the beasts final destination The Nest.
