Dr. Selma Ruiz had spent her entire career trying to finish the great ambition of her father, the archeaologist Benicio Ruiz—reuniting the mythical Aztec serpent cuffs. If she had translated the writings correctly, when she slipped them on, she would be granted the powers of the moon goddess Metztli. After being trapped in metaphysical exile for millenia, however, Metztli was in no mood to lend out her powers to a mortal, so she instead took Dr Ruiz’ body for her own.
