Antimony is a stone eater who appears as a woman with pale skin and black and dark-red hair and eyes. She is especially attached to Alabaster, occasionally visiting him for several years before saving him and Syenite from the destruction at Allia by bringing them to Meov. When Meov is being attacked by the Guardians, she drags Alabaster into the earth against his will, presumably to save his life once more. Antimony is present as Alabaster destroys Yumenes and also when Essun finally reunites with him at Castrima—but she has seemingly been eating Alabaster’s limbs as they slowly turn into stone.
