rest of the solar system and to colony worlds in four other star systems accessible through FTL stargates. All humans living "beyond planetary atmospheres" are claimed as subjects of the corporation-dominated Rightly Guided Stellar Caliphate (which did so ostensibly to preserve humanity in case the fighting on Earth became genocidal in nature). Along with the reality of extraterrestrial life, the Stellar Caliphs also recently developed mainframe artificial intelligence agents called djinn, who are accepted as equals in Muslim society. Aeolus Aeolus breaks with our history in 1688, when the favourable winds which allowed William of Orange to safely cross the English Channel and invade England in the real world never materialized and his fleet was lost in the attempt. King James II was therefore never driven from his throne, and subsequently executed the anti-Catholic parliamentarians who had invited William to take the throne for treason. After this victory, James' Catholic sympathies were displayed openly as he ignored Parliament and allied with France. The eventual reunion of the Church of England with the Church of Rome in 1745 drove British Protestants to North America en masse; a series of succession crises and wars throughout the 19th century left 20th century Europe discontented and dissatisfied. Central Europe experienced a series of republican revolutions in the 1940s; the Republican Alliance that emerged is pinned between the Habsburg Dominions across northern Eurasia and the Bourbon Dominions of western Europe. In North America the Kingdom of Louisiane under the House of Orleans controls the most territory, though the Grand Duchy of Aleska and Mexique are also of considerable size. The American Commonwealth, a near-theocratic Protestant nation governed by a Lord Protector appointed for life, is smaller, of a size with Nouvelle France, the sole remaining colonial possession in North America. The character of Aeolus is of a world with near-modern technology (the "current year" is 1941) in which political thought is many years behind its course of development in our world. Fortunately for the Republican Alliance, the presence of Mikhail Gurevich and Henri Coanda has given them sole possession of jet aircraft technology and, indeed, the only airplanes on the planet. Centrum Centrum is detailed in Alternate Earths II in greater detail than before in the GURPS line. Its point of divergence is the successful crossing of the White Ship, meaning that William Adelin, the sole male heir of King Henry I of England, was
