In a distant future, humanity has expanded across the stars, blending with countless alien species and their technologies. The human body, becomes the universal template, enhanced with nanoscale cybernetics and odd bits from other species, making individual races into something more than human.

The protagonist wakes up in some ruined city, no clue how he got there, everything around him falling apart, poisoned air thick in the streets. His body’s augmented, though he doesn’t quite get how, and there’s this AI companion in his head, teasing him along, as lost as he is. Together, they wander through the crumbling streets, piecing together what happened to the city, and to them.

Long after, a relic-hunting girl and her crew stumble upon his preserved memories, pulling them into a mystery that spans aeons. As both timelines intertwine, they uncover a hidden force that has shaped their fates across time, binding past and future in ways none of them could have foreseen.
