The newest Hearth & Horizon story, Thirty Seconds and Thirty Minutes, is fiction: the hill, the parish and the people are invented.

Sound travels about three seconds per kilometre, so counting from flash to bang gives distance. In the story a count of 41 seconds at 14:10 (about 14 km) and 27 seconds at 14:20 (about 9 km) puts the storm 5 km closer in ten minutes, 30 km/h, and overhead in about 18 minutes. The median walk down the hill takes 50 minutes, so not everyone can outrun it. That is the point: a rule written beforehand (move at 30 seconds, wait 30 minutes after the last thunder) sorts people between a chapel with a tested lightning rod, a barn, vehicles and the path, and the steward's assistant says plainly that no place is safe, only less exposed.

The facts behind it are standard public guidance: the 30-30 rule, strokes reaching 10 km or more from a storm, a metal-roofed car or a protected building as shelter, and crouching in the open not making anyone safe. The speeds, crowd numbers and the 9-ohm earth reading are invented for the story. It is not safety advice for your hill; follow your national weather service. The story is text only for now.
