There are legends of a wanderer who has appeared over the centuries. He is usually called a wizard, but sometimes he is called a physician. The descriptions of him very and the only way to know if it is him is by a blue box that he travels with. But all good legends are based in some fact.

Constructive criticism welcomed, after all I can't fix something if I don't know it's broken.
