Argent spiders resemble normal spiders in form, but they are composed of crystalline materials and metals, and are silvery gray-green in color. It seems as though they have been sculpted into a perverse form of art, but they are living creatures. Nobody can say how this vermin came into being, but it is a fairly common sight on the Demiplane of Ectoplasm.
