Note: The Wire Rod and Flame Wand are required. In the southwest corner of the map is a graveyard. Examine your minimap and you'll see that one of the graves is not marked by a dot. The grave in question is one over (west) and three up (north) from the southeast corner of the graveyard. Push this gravestone upwards to reveal a passage leading down, then speak with the Hero's ghost in the grave to receive the awesome Hero's Sword.
