successor states were ill-equipped to resist subsequent barbarian invasions. In the "current year" of 1848, the expansionist, steam-powered Tenochca Empire faces off against the Hotinohsavannih League to the north and the Songhay Empire (the last remnant of Roman culture) to the east; whoever wins is likely fated to take on the somnolent but fearsomely large Mongol Khaganate that covers most of Eurasia. Friedrich This parallel world is named for the Holy Roman Emperor Friedrich I Barbarossa, who in this timeline managed to be the great imperial unifier and conqueror that the vagaries of fortune prevented him from being in our history. In "current year" 1219, seventeen years after his death, Friedrich is notable for being a hotbed of activity by the SS Raven Division from the Nazi-dominated parallel Reich-5, who seek to turn his Holy Roman Empire into a First Reich and breeding ground for Aryan warriors. Gallatin Gallatin is named for Albert Gallatin, the dominant member of Thomas Jefferson's government due to Alexander Hamilton having died in the Battle of Trenton. Without Hamilton to defend and explain the United States Constitution in the Federalist Papers, it was never ratified and the independent colonies balkanized into nine separate republics across the continent by 1860. In "current year" 2004, Gallatin's great powers include Texas (whose nuclear arsenal shields the other libertarian American republics), German-dominated Europaverein, the British Empire, the Soviet Union, and the Japanese Empire; peace is maintained by the fear of mutual destruction in an atomic war. Gernsback This parallel world is named after editor Hugo Gernsback, due to the futuristic architecture and technology being used there. The divergence happened in 1893, when Nikola Tesla married Anne Morgan, daughter of millionaire and philanthropist J. P. Morgan, an event that helped him to stabilize his life and make many of his inventions reality thanks to the support of his father-in-law. In 1902, he created a radio tower that broadcast to the entire world from Long Island, and he later managed to develop wireless electricity broadcasting, which eventually helped Germany to stabilize and avoid falling under the control of Adolf Hitler and Nazism, and strengthening the League of Nations, avoiding World War II. When, in 1951, Andrei Sakharov managed to defect to the West and tell of Stalin's plans to create atomic weapons, the League of Nations declared war on the Soviet Union, which fell on April 30, 1953, with the death
