Speaker for the Dead Edit
After the death of her "father" Marcos Maria Ribeira, she became withdrawn, barely saying anything outside of her family for months. When Andrew Wiggin came from Trondheim after answering Novinha's call for a Speaker for the Dead 22 years earlier, she startled the family by telling the Speaker that he stunk.
Five years prior, Quara began studying the Descolada and its apparent intelligence, originally trying to find a way to inhibit or destroy it before it killed the humans. During her studies, she discovered what she believed to be proof that the Descolada was sentient - carrier messages the viruses voluntarily sent to each other. She fought with her family against destroying the molecule, arguing it was xenocide to destroy a species that was "sentient". She finally caved in to the pressure upon her when a Pequenino named Planter underwent an experiment to determine whether or not the Pequeninos were intelligent before the Descolada came.
