 What characteristics best describe Captain Llud in the present part of the story?
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. Knof Llud, the Quest III's captain, came slowly down the narrow stair from the observatory, into the big rotunda that was now the main recreation room, where most of the people gathered. Eyes lifted from the vision screens to interrogate Knof Llud; he met them with an impassive countenance, and announced quietly, "We've sighted Earth." 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. Now the last fuel compartment was almost empty and Captain Knof Llud felt tired and old. 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. "One light-day out from Procyon, the thirty-third day by ship's time since leaving Earth. Our generation's dream, humanity's dream, lives in us and in the ship forever...." Presently Knof Llud switched off that younger voice of his and leaned back, an ironic smile touching his lips. "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. This may be man's last chance of escaping his pitiful limitation to one world in all the Universe. 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. "Looked at historically, such super-human outbursts of energy are the result of a population's outgrowing its room and resources, and therefore signalize the beginning of the end.
