September 1859. After the strange solar storm, the city waits in tense silence: a centuries-old threat is about to come to fruition.

In the quiet, the tapping of a gruff, meddlesome man’s cane echoes. Beside him walks a young blind woman who can see what no one else can. Together, they form an unusual investigative duo: reason against intuition, science against belief. A new clue will lead them to a secluded asylum—and that will be just the beginning.

A disturbing mechanism reveals itself as a map; encrypted messages, scraps of paper written in blood and ashes; images burned into stone walls that shift over the course of days… The relentless Hermetic Society advances its Plan in the shadows.
