From the back cover: Almost a century ago, against the better advice of the Hegemony, the Solar Witnesses despatched the Revelation - an antimatter torch ship - on a pilgrimage to the Machine Civilisation Polis in the Altair star system. IT NEVER CAME BACK. THAT IS, UNTIL NOW. Publisher blurb: The Last Witness is a self-contained adventure for River of Heaven, a search and rescue mission out in the black tombs of space far from home. It uses the default campaign background but with a little work can easily be translated to another setting. While being quite self-contained, it still has potential as the starting point for a campaign. It comes with six pre-generated player characters.
