Heaven's Wake
Heaven's Wake is a hard science fiction SD (with one exception) set in a post-apocalyptic environment. You are one of many polities to have survived the collapse of the post-human civilization that underpinned and nurtured humanity. Taking place in a region of space known as the Reconnect, the SD focuses on exploration and expansion as civilization recovers enough to look outward.
Every Player character is a nation that has been reconnected by the 4th Jupiter Republic's Reconnection Flotilla.
As the Reconnect expands, the technology of posthumanity is coming under scrutiny, as ways are developed to exploit it and lift it from it's dormant state. The enduring mystery surrounding the collapse has also weaved it's way into the consciousness of known space and influences it's politics in a myriad of ways, some more sinister than others. Chief among some concerns is the fate of the Solar System while others couldn't be less concerned with such a distant and irrelevant system, not least when compared to the pressing concerns of the immediate.
Others still gaze upon the mystery of the dark roads, a parallel system of transport gates that lead to the mysterious megastructure. There is much technology and wealth here, but danger in equal parts.
