The Timeblazers head back to about the year 700 in Western Europe and learn about the Franks, Visigoths, Saxons, and the Vikings and that only monks or friars read books. These were considered the Dark Ages. However, in other places, like ancient Baghdad, Mohammad Bin Musa Al Khwarizmi invented algebra; people in the East also invented a qanat, which was an underwater channel system; and hospitals. In Central America the Timeblazers learn that the Mayan civilization was advanced and invented the 365-day calendar. In 1450, Johannes Gutenberg invented the printing press and people everywhere were able to read, which finally ended the Dark Ages.
