The Ealdremen System is a binary star system located in the God's Path Arm of the Wyretorra Galaxy, though for much of its history, its inhabitants believed erroneously that their system had only one sun, either the sun Topple-King for civilizations located kingsward or the sun Usurper for civilizations that lie kingsaway. Ealdremen is home to a multitude of habitable planets, many of which have multiple examples of species achieving sentience, sapience, and eventual society. It is characterized by usage of advanced technology and magic from a recent bygone age known as the Millennial Calm, a then-unprecedented era of peace and innovation that came to an abrupt end with a system-wide apocalyptic event.
