Turn back time

There were dragons, thousands of years ago. Although all dragons and people weren't always best of friends, many of them were.
But... What would happen if dragons somehow found themselves in our modern world. What would happen once they found the cities, the farms and schools? A national panic would be triggered and a war would be waged.
Shortly after Grimmel was defeated, a time warp opened up and sucked several of the dragon riders in. Now its up to one girl to keep them a secret in the mountains and keep the balance of society until they can find a way home.
