Mongols: China, Tamerlane and the New Iran
The Ming dynasty has finally overthrown the Yuan Mongols of China. The kahnate of Kublai Khan is no more but in this chaos, there is opportunity. Tamerlane has taken the throne of Samarkand in current day Uzbekistan and is using his position to "help" the Mongols of the neighboring khanates. In this year and the next, Tamerlane will begin his moves to take western Asia. He will use a simple system to count his battle losses. Before a battle, small stones are counted out in a pile and each soldier picks up a stone. After the battle they return the stones to the pile and the stones are counted. The difference in the stone counts mark the number of men Tamerlane lost in a battle.  
Why Charles is called Wise
In the modern day, the Louvre is best known as the French art gallery where the Mona Lisa resides but the Louvre won't become an art gallery until 1678. In 1368, it is a fortress in the process of becoming the royal residence. King Charles the Wise of France has now established a library in the Louvre. A candle will remain lit at all times so that the King may read. He will commission translations of the Great Works such as those of St. Augustine and Euclid. He will also have Nicolas Oresme, a scientist, produce a plain language explanation on the theory of a stable currency. Claude Mallet, the king's valet de chambre (a position reserved for artists, musicians and the like), will serve as the first librarian.
