chunk: Tropile now finds he is a hero of sorts, but does not fit the role (though he never truly fit any role in which he was placed - Sheep, Wolf, or Component). He also sees that there is a need for someone to wire themselves back in to the alien planet's surviving systems, to re-kindle the 'sun' every five years and perhaps return the Earth to its original orbit. He doesn't want to do it alone, but most of the people he knows are either unwilling or unsuitable. On the last page, though, his wife agrees to join him. He expects that there will later be others, that "[t]he ring of fire [will] grow."
