The Chalders had battled their way to the top of their evolutionary underwater tree, learned to survive and later to control and utilize the power from their undersea volcanic activity while husbanding the living, nonsapient resources of the most beautiful world in the Federation, although the small-eyed air-breathers like himself required pressure vessels and visual enhancement to appreciate it. They were already a highly civilized species before their discovery of fire and the beginnings of the technology that enabled the very few of their number to fly through the near-vacuum above their ocean and into the space beyond. But no matter how far or often they traveled or their reasons for doing so, they remained a part of Chalderescol’s mother ocean and needed periodically to return to it.
Considering their enormous body mass, the size and complexity of life-support required, and the extreme danger and discomfort involved in traveling in space, Hewlitt wondered why they did not stay at home.
“Why does any otherwise sane person want to travel in space?” said Two-Eleven, making him realize that he had been wondering aloud. “That is a very large philosophical question, and much too complex for debate if you still want to speak to the other patients before the lunch hunt begins. Hold on to my fin again …”
His experience with the first three Chalders meant that he was able to speak briefly to the other patients with some understanding of their feelings, or at least without making a complete fool of himself. He stopped beside but did not speak to the gravely ill patient Lioren was visiting, because they were already having a conversation and he thought it better not to intrude. But from his moment of floating beside its treatment frame he was able to establish that it, along with the rest of the ward’s other patients and medical staff, had never been hosts of the virus creature.
He returned to find the food-dispenser outlet beside the nurses’ station open and, drifting horizontally in the water before it, what seemed like more than a hundred flattened, ovoid shapes just under a meter in diameter. Their upper surfaces were covered by irregular patches of dull color while the underside was pale grey. A long, low dorsal fin ran fore and aft, and the rim at the stern was pierced by three circular openings. While he was moving forward for a closer look his hand touched the object, sending it into a slow roll. Suddenly Charge Nurse Hredlichli was beside him.
“What … ?” began Hewlitt, and broke off as a shapeless, Illensan limb shot forward, grasped the object, and pulled it level again.
“Do not alter the trajectory,” it said in its usual impatient voice. “For your information, if you do not already have the knowledge, that is a container of concentrated food enclosed in an edible shell and propelled by concealed capsules of high-pressure, nontoxic gas which simulates the movement through water of a fleeing, nonsapient native crustacean. It has been found that mobile food increases the patients’ appetite and has beneficial psychological effects. If the food vehicle were to crash edge-on into a wall or deck and burst, it would leave a mess that my nurses would have to filter out and remove when there are more important duties requiring their attention. Please reenter the nurses’ station and stay out of my head fronds. Patients, your attention please …”
Its voice was coming from the ward’s wall speakers as well as his headset, and Hewlitt was being ignored.
“The main lunch release is imminent,” Hredlichli went on. “It will be followed in fifteen minutes by the containers marked with concentric blue circles, which are the special diets required by Patients One-Ninety-Three, Two-Eleven, and Two-Fifteen. Kindly remember that these are not to be consumed by anyone else. Patients confined to their treatment frames will have lunch delivered to them by the nurses once the mobile patients are fed. All medical staff who are not already in the nurses’ station return there at once. Padre Lioren, this includes you.”
Lioren returned but did not seem disposed to speak to anyone. Perhaps its mind was still on its sick patient. Hewlitt watched as fans of bubbles jetted from the sterns of the lunch vehicles and they began to accelerate down the ward, their numbers thinned by heavy, darting shapes and clashing jaws. The shape of Hredlichli, looking like a grotesque, plastic-wrapped sickly vegetable, was still drifting close by, and for the first time since his arrival it seemed to have nothing to do.
