The Tinker
There are many theories as to why the Tinker plays such a pivotal role in folklore. From Feltemi's well intentioned but ultimately misguided economic theories, to Delposet's ridiculous tripe about their prophetic powers. The truth of the matter should be simple for any clear thinking individual: Tinkers are a sign of civilization.
Where the roads are safe, Tinkers travel freely, bringing welcome news and many necessary goods that are hard for to come by in small towns. Small wonder that when people see a Tinker, their hearts rise and they rejoice. It is a sign that all is right in the world.
