Planter wanted to know whether or not the Pequeninos were intelligent before the Descolada altered them. As a way to prove that his people did not need the virus for sentience, he took part in an experiment that removed the it from his body. After spending several hours in a decontaminated room reciting stories, he died sane. Almost immediately after, several Pequenino scientists quickly removed him from the decontaminated room and planted him. However, due to his body lacking the virus, Planter became a Brother Tree, incapable of communication or consciousness.
