The Hearth Flame is the single most important object in The Last Hearth, so it was the first thing we built for real. The rules are deliberately simple: fuel goes in, and a circle of protected ground comes out. Stand inside it at night and the Veil cannot reach you. Step outside and you are on your own. What makes it interesting is that fuel is never free. Wood is plentiful but burns fast. Furniture burns longer but you only have so many chairs. And the things that burn longest are the things you least want to give up — a keepsake, a signpost, a door that was keeping something out. Every playtest so far has ended the same way: someone, deep in a bad night, feeds something irreplaceable into the fire because the alternative is worse. That feeling — the small, specific regret of it — is exactly what the whole game is built to produce. The prototype proves the loop generates it on its own, without us scripting a single moment.
