Dracula is Dead... for Now
Vlad the 3rd the Impaler is more commonly known as Dracula... that is... Son of the Dragon. The King of Hungary had established a special Christian Order of the Dragon, pledged to fight the Ottoman Turks. Vlad the 2nd was a member of the Order and was given the name Dracul. Vlad the 3rd, being his son, was called Dracula. Dracula was a very good Ottoman killer. He would drain the blood from the bodies of his enemies and leave them impaled on wooden stakes. In this year he has organized several armies to hit the Ottomans once again but his fortunes take a turn for the worst. He dies in battle near Bucharest. It is not clear how he dies, but the Ottomans find his body and send Dracula's head to the Sultan. The Sultan has the head raised on a pike. While he remains an infamous figure to most of the world, Romania has embraced him as a hero.   
The Plague Kills the Calendar Fix
Johann Müller is a German astronomer and the son of a miller... which is probably why his last name is "Müller." However, he is best known as Regiomontanus [ree-gee-oh-mon-TAY-nus] which means "king's mountain." It is the place of his birth. It's like being born in Laredo and thereafter being known as "The Man from Laredo." He has learned Greek so that he can study the ancient astronomy books in the original. He has also studied what is now known as Halley's comet. It is the first time such objects are studied in a formal manner instead of being seen as an omen. He has become so famous that he has been summoned by the Pope to help fix the Julian calendar. Unfortunately, the Black Death will take him this year in Rome. A fix for the calendar is DENIED!
