[b]Calypse[/b] [i]Imperial Capital/Homeworld; Milky Way[/i] Diameter: 14,263 kilometres Length of day 24.0 hours Length of year 365 days (local) Gravity 1.00 G Atmosphere 1 (Oxygen, Nitrogen) Temperature: -26°C to 42°C (-15°F to 108°F) History: Terraformed to be almost identical to humanity's mythical homeworld of Earth, Calypse served as the birthplace of the Empire. After the Emperor united the Coalition systems under his banner, he declared the then-inhospitable world of Calypse to be his capital, terraforming it as an example of how powerful, yet benign his fledgling Empire could be. As the Empire began to expand, Calypse became the center of government, and home to one of the largest civilian populaces in the Milky Way. When the Sol Alliance invaded, and the Empire began to crumble, all mentions of Calypse and its location were hidden, and the entire system was sealed off by an array of slipspace anomalies, where it became the home of the Imperial Military. Centuries later, when the Dread finally discovered this system, Calypse was destroyed by the titanic battle than ensued, marking the end of Imperial dominance over the Milky Way, leaving Helios as the last bastion of the Empire.
