Building the grounded world
Low fantasy's supernatural elements only feel genuinely strange when the ordinary world they intrude on feels genuinely real. This means investing in realistic detail — the specific textures of a specific place and time, the economic realities that shape characters' choices, the ordinary social interactions that establish what normal looks like in this world — before introducing the supernatural. The real world must be convincing on its own terms before it can serve as the backdrop against which the extraordinary registers as extraordinary. Authors who rush to the magic before establishing the grounded world find that their supernatural elements feel like genre furniture rather than genuine intrusions.
