Ruth Xenobia worked in the storefront of her grandmother, Madame Xenobia. Spider-Man visited the store as his alter ego, Peter Parker, seeking information on a tarot spread in order to help Doctor Strange, who had been transformed by a curse into a werewolf, Madame Xenobia, more adept at palmistry, asked for assistance from Ruth, whose specialty was cartomancy (divination using tarot cards). Ruth interpreted the cards for Peter, who left the store, satisfied.
