Ferrezza is a single blue star in the Jansamei region. It has three major planets and 787 minor bodies.

During the Post-War Era, the system was chosen as the site of a large-scale data processing operation, overseen by a powerful AI. Over time, the project expanded, along with the station dedicated to it, until it became a city-sized labyrinth of processing hardware.

Following the Upload, the AI was left to its own devices. Travellers came to it, seeking its wisdom, and it was happy to oblige. Eventually, its wisdom became law, and this law spread to many systems around it, and these systems became the Blue Empire, ruled by the AI from its place in the heart of what is now known as the Azure Palace.
