Sol System

The Solar System (also called the Sol system or simply Sol) is the planetary system inhabited by humanity. During the Golden Age, humanity forged an empire that spanned much of the system, but the catastrophic effects of the Collapse forced humans to retreat to Earth, abandoning their many worlds to various other forces.

The planets and the Sun of the Solar System are each associated with one of the dark-matter based intelligences that collectively make up the Nine.

The system is currently inhabited by both the Traveler and the Darkness, the latter of which is in the midst of sieging the system.
