Location from Resident Evil 4 by Capcom
Not one place but many — the Merchant's safe havens appear throughout the game, always where you need them, never where the enemies can reach.
The Merchant's shops are the game's save points and breathers. They appear before and after major encounters, giving the player a chance to upgrade weapons, buy supplies, and sell treasures. The blue flame is a Pavlovian comfort signal — players learn to associate it with safety. The impossible logistics of these shops are part of the Merchant's mystery. He has military-grade weapons in a medieval castle. He has rocket launchers on a remote island. He sets up shop in places that require navigating through hostile territory that he somehow bypasses. The game never explains it, and the community loves the mystery. The shops are gameplay necessity elevated to world-building charm.
A blue flame lantern marks every Merchant location — visible from a distance, a beacon of safety. The actual spaces vary: a back room in a village house, a hidden alcove in the castle, a supply room on the island. Each is inexplicably stocked with weapons, ammunition, first aid, and treasures displayed on blue cloth. The Merchant himself stands behind an informal counter, trenchcoat spread to display his wares.
