Pluto is a dwarf planet in the solar system, belonging to the Greater German Reich as a colony for "Untermenschen."
In 1949, Reich Minister of Space Hermann Goring proposed that Pluto be used as a deposit for "Undesirables." Several of the Reich leaders, including Adolf Hitler, agreed to the plan, stating it was far easier to simply deport them there. Hitler arranged for a small base to be planted on Pluto, with an observatory placed on the major moon of the planet, Reichsauge.
Upon the first arrival of Jews in 1950, the survivors of the brutal journey quickly began setting up a government. The first president of this "Republic of Pluto" was Mordechai Anielewicz, who served until his death in 1960.
Throughout the 1960s and 1970s, Pluto became home to several prominent dissident authors, who emigrated to the planetoid for refuge. The first of these authors was Elie Wiesel, critic of Reich policies. Oddly enough, the Reich Ministry of Public Enlightenment tolerated such writers, provided they never left Pluto. This lead to the flourishing of the culture on the planetoid, leading to the rise of authors such as Harry Turtledove.
Pluto also became a covert base for the French Resistance under Charles de Gaulle, cybernetically enhanced with machinery stolen from the Reich. Several Jews on the planetoid joined the resistance, and helped harass Reich shipping.
