In Roman mythology, Orbona was the goddess who granted new children to parents who had become childless. She was also the goddess of children, especially orphans.
Early Roman Mythology focused on the interlocking and complex interrelations between gods and humans. In this, the Romans maintained a large selection of divinities with unusually specific areas of authority. A sub-group of deities covered the general realm of infancy and childhood. In this area, Orbona was called upon as a general guardian and tutelary deity of children and orphans.
In Tony DiTerlizzi's book "The Search for Wondla," Orbona is the name of the planet that serves as the setting for the story. The human girl, Eva Nine, carries out a perilous search for others of her kind, accompanied by a caretaker robot and two friendly denizens of the planet.
