Modern-day New York City is one vast, living sealing array. The Metropolitan Museum's central exhibition hall is in fact the array's core; Trinity College is an "observation station" dedicated to monitoring the inheritors of divine blood. The modern city humans live in is a false shell manufactured by the Night Clan through their "Mist System"; beneath it lies an ancient bloodline network and forgotten altars. Five spaces exist layered across overlapping dimensions: - **The Modern City**: A civilization disguised as the power grid, in truth suppressing the frequency of the old gods through electricity. - **The Museum**: Holds the dismantled fragments of divine bodies — what are passed off as "artifacts." - **The Academy**: Its archives record the bloodline purity of every student; those whose purity runs too high are "cleaned." - **The Ancient Ruins**: Abandoned subway stations beneath the city, the last refuge where the old gods' rules still linger. - **The Sealed Space**: The code-layer beneath collapsed reality, filled with floating dark-gothic runes. When the male lead — an anomaly abandoned by the System — and the female lead — a Calibrator carrying a resonant bloodline — come together, the shell of reality will shatter like broken glass.
