This is where it all happens, citizen! The white-heat of hyperadvanced technology! The teeming populations of the many worlds of Manhome, the ancient solar system, cradle of humankind! The thousands of worlds of the Old Commonality, drenched in byzantine intrigue, the strange and divergent hominids, the products of millennia of change. We’re all what the past has made us. But what we will be, and where we are going… that’s what we’re fighting for!”

Welcome to the mind-blowing worlds of the Commonality Core—humankind’s most ancient and advanced civilisation. A people of deep yet divergent cultures, riven by the shock of contact with new and rediscovered worlds. The Core Worlds are where humankind began—but now, after ten thousand years or more, maybe they’re no longer human at all…

The Core Worlds Sourcebook details a vast sector of Commonality Space for your Mindjammer games. Focussing for the first time on the ancient, decadent, and sophisticated heart of the Commonality, it provides you with deep background and material to explore this fascinating region. Play Fringe Worlders experiencing the strangeness of the Core first-hand, or Core Worlders, sure of their superiority, until they leave their homes and are found wanting. Play planetary sentiences ruling whole worlds, ancient dynasties with plans crossing millennia, illegal xenomorphs fighting oppression and neglect in the forbidden substrates beneath the towering arcologies. Push the boundaries of transhuman science-fiction gaming—explore what it means to be human itself. A bright, bizarre, and thought-provoking milieu for your Mindjammer games!
