Proserpina
From Gineipaedia, the Legend of Galactic Heroes wiki
Prosperina is a world within the Galactic Empire. One of the earliest colony worlds, Prosperina played a major role in the Earth-Sirius War.
History
After Rondolina fell to the Space Force of the United Earth Government in 2689 CE, many members of the Sirius Revolutionary Congress fled to Prosperina where they helped to organize the Anti-Earth Movement into a force capable of fighting the UEG on equal terms.
In 2691 CE, Carle Palmgren, Winslow Kennes Townshent, Joliot Frankul and Chao Yuiling all met each other for the first time on Prosperina. There, they quickly became the leaders of the Anti-Earth Movement and founded the Black Fleet. Prosperina would serve as the headquarters for the Black Fleet and the beating heart of the anti-Earth resistance movement until the eventual liberation of Rondolina, some time prior to 2703 CE.
