The Town as Antagonist
In small town horror, the setting is not backdrop, it is a character with agency and history. Your town should have a specific geography that shapes the story: the road that is always foggy, the woods everyone avoids, the building in the center of town that holds the community's secret. Give the town a past that explains its present, something that happened decades ago that still shapes every relationship and every unspoken rule. The town should feel like it is watching your protagonist. Every landmark, every local tradition, every community gathering should carry a faint wrongness that the reader cannot quite name.
