Inventio Fortunata (lost travelogue, 14th century)

Inventio Fortunata (translated to Fortunate, or fortune-making, discovery) was a 14th-century travelogue written by a Franciscan Priest from Oxford. The travelogue is unique as it describes the North Pole as being magnetic and made up of four separate continents. The book was presented to Edward III of England in 1360 as a present. Fragments of Inventio Fortunata were re-written by Dutch writer Jacobus Cnoyen who extensively copied fragments. These were later sent in a letter and sent it to John Dee. The letter is now in the only piece of evidence that gives a context as to what was in the book. The last time the book was mentioned was in a letter dated 1497 from English merchant John Day, who claimed that the book was found in Spain. To this day, none of the books, not even a single fragment of them, have resurfaced and the last time it was seen was in the 15th century.

Background
The Medieval ages saw intercontinental trade survive on old Roman roads. These old roads saw Western Europe become more with Eastern Europe and the rest of the world as Eastern European Kings like John of Bohemia traveled to Western European cities. Crusaders traveled into Northern Europe in order to introduce Christianity. Viking established colonies in Iceland, Greenland, and Canada and Merchants such as Marco Polo traveled to China.

Contents
Contents from a few second-hand sources who saw the Inventio Fortunata describe an English priest who is driven to investigate the North. In his travels, he finds a place called the "Ilse of Dwarves" which are inhabited by men with very long feet. Further is in the book, the man finds a vast continent at the pole that is divided by rivers moving so fast, they don't freeze at the arctic's chill. At the center of the pole sits a black magnetic rock that is 33 miles around and to which all compasses point to. After leaving the land, the priest returns to England and gives the report to the king.
