The young Lord Occam settles at the mouth of the river Sarum and constructs a castle on an island in the river. Inland, a small settlement begins to take shape, taming the wild land of great forests. Despite hardships, the town grows and attracts both settlers, merchants and villains. Illustrated with images from the game of Minecraft, the Medieval trading post slowly comes to life in a distinctive graphics style.

The book is the result of the inspiration of the great game of Minecraft as well as an attempt to tell stories using the graphics of the game as illustrations. At the same time this story is an experiment of a historian interpreting northern European early Medieval city history in another way than a normal textbook would. The development of the settlement is inspired by the historic cities such as Copenhagen, Lübeck, Hamburg and Stockholm.
