England, first years of 19th century.
Once upon a time there was a village near to Birmingham, in the countyside. They called it Buttudonua. Now that village doesn't exist more, due the industrial revolution.
The village was built near to a small river, whose water, as they said, had magical powers. It had small stone house and farms. Somone tells that, in one of theese houses lived a wizard family, that knew how to use the water of the river and some secret spices in the better way to make magical potions.
They say that often in the village occurred transformation of every kind.
Nobody really knew what was the wizard family, or if there really was one, or if were more femily than one, or if there was only a people that can use magic. But I suspect we can learn to recognize that people due to this tale.
