In 2067, memory is no longer a private sanctuary. It is a programmable frequency.

When Patricia Ferme travels to a fog-buried estate in the mountains of Asturias after the disappearance of her grandfather, Lucas Vireaux, she expects only to settle his affairs and grieve in quiet. Instead, she finds the remnants of his final work: a hidden laboratory where sound, memory, and consciousness have been drawn dangerously close.

Lucas was more than a reclusive composer and neuro-acoustic pioneer. He believed memory was not stored, but enacted—carried through rhythm, attention, kinship, and place. What he left behind is a manuscript encoded with grief, a sentient interface, and an invention capable of opening consciousness to lives buried far deeper than history.

As Patricia is drawn into the world of Vala, a Neolithic seer whose rituals reveal the earliest grammar of human belonging, she begins to understand the true danger of Lucas’s work. Powerful forces now seek to control memory itself, reshaping identity through synthetic cognition and erasing those who fall outside its design.

Spanning deep prehistory, a fractured future, and the haunted landscapes of northern Spain, That Which Remembers Us asks: What remains of the self when remembrance becomes a technology? And what are we willing to sacrifice to preserve what we love?
