Running from New Aries’ many dangerous life-forms, they are eventually found by the Locals. They are enraged by the attempted capture of the tiny Willis. In the end, only Jim and Willis’ friendship save the colony world from destruction by the angered natives, who reveal themselves to be an intelligent, highly advanced subterranean race. Willis then tells Jim that it is time for him to go. He is finished being a child, and must become an adult via metamorphosis. One of the colony’s doctors correctly assumed that Willis was not a separate species from the Locals, but rather a Local in its infant form. Jim says that he will wait for Willis to finish changing, but Willis states that this will take a long, long time. He and Jim will probably never see one another again. Many decades later, New Aries has been terraformed into a green, Earth-like world, with humans and Locals living side by side in peace. Willis, now a full-grown Local, has befriended Jim’s young granddaughter, and spends time with her wandering the grass-covered hills and telling her stories of the adventures he and her grandfather had together.
