Blacksmith working the bellows is an unnamed NPC who can be found next to the Lumbridge furnace east of the Combat Academy, where he helps to keep the public furnace running. Unlike most non-player characters, the blacksmith cannot be spoken or interacted with, although he can be examined. He is classed as an object not an NPC and as a result he does not appear as a yellow dot on the minimap. The blacksmith himself does not help to explain smithing to new players, and as a result he serves only to add realism to the game.
