Silence doesn't vanish when you break it - it learns how to wait differently.
Greyhaven has survived the Quiet once, twice, and now learns that safety hums. The shrine is gone, the sentinel stands, and the townspeople have learned to name their own movements aloud. But something remains: a residual tone, a faint remnant that refuses to fade.
Season Four is about what happens after survival - how people live beside the residue of what once tried to claim them. It's a story about maintenance, fatigue, and the dangerous comfort of habit. The Quiet has become a civic religion now, and the living must decide whether vigilance is salvation or simply another form of captivity.
