You see Rukrell Tethlul the Gnome Tinkerer.
He appears to be in his 80's, has lank, oily black hair, ghostly silver-blue eyes, and oily soot-covered skin.
He is in good shape.
He is wearing a canvas toolkit, a double strapped harness, a weathered satchel, some oily cotton overalls, and a pair of magnified spectacles.
