Look for caves that old folks swear have been echoing with ghostly wails for centuries. The ones that lie in abandoned mines or along cliff edges, where the wind whistles like mourners, often hold the most weather‑worn stones. Keep your lantern low, avoid the main shaft if you can, and trust your gut—those rocks usually feel a little too heavy with history. If you’re brave enough, slip into a side tunnel after sunset and you might catch a chill running down your spine before you even find the stone. Good luck, and watch out for those caves that think they’re still echoing with the dead.
