 From the information the story provides, do you think you have a good sense of the personalities of Captain Llud's crew?
In the last hours the star ahead had grown brighter by many magnitudes, and had changed its color from a dazzling blue through white to the normal yellow, of a GO sun. Eyes lifted from the vision screens to interrogate Knof Llud; he met them with an impassive countenance, and announced quietly, "We've sighted Earth." After all, it's only been nine hundred years." Llud nodded curt approval, remarking, "Probably we'll be intercepted before we get that far." From his private office-cabin, he sent a message to Chief Astronomer Zost Relyul to notify him as soon as Earth's surface features became clear; then he sat idle, alone with his thoughts. The ship's automatic mechanisms had scant need of tending; Knof Llud found himself wishing that he could find some back-breaking task for everyone on board, himself included, to fill up the hours that remained. Perhaps, he thought, he was feeling the weight of his nine hundred Earth years—though physically he was only forty now, ten years older than when the voyage had begun. Bemusedly Llud got to his feet and stood surveying a cabinet with built-in voice recorder and pigeonholes for records. "Our visit to Procyon drew a blank. If success comes there, a century will have passed before we can return to Earth; friends, relatives, all the generation that launched the Quest ships will be long since dead. Our generation's dream, humanity's dream, lives in us and in the ship forever...." "One week since we passed close enough to Aldebaran to ascertain that that system, too, is devoid of planets. "We face the unpleasant realization that what was feared is probably true—that worlds such as the Sun's are a rare accident, and that we may complete our search without finding even one new Earth. Certainly the building of this ship and its two sisters, the immense expenditure of time and labor and energy stores that went into them, left Earth's economy drained and exhausted. Now we turn back along a curve that will take us past many more stars and stellar systems—but hope is small that any of those will prove a home for man, as have none of the thousands of stars examined already. We have only, as it were, visited a handful of the outlying villages of the Universe, while the lights of its great cities still blaze far ahead along the Milky Way. "That was why the planners limited our voyage, and those of the other Quests , to less than a thousand years Earth time.
 No. Llud was well-described, and some of the side characters had detail, but none of them really stand out too much.
 Probably. There were good descriptions for all of the side characters, including Captain Llud's son.  No. Llud barely spoke to anyone on the ship at all, he was even ignoring his son so we really didn't get to see a good glimpse of anyone's personalities.  No. Llud was well-described, and some of the side characters had detail, but none of them really stand out too much.  Yes. All of the characters felt incredibly real, and they all care deeply about Llud.
