This could be a fascinating speculation, Kworn thought. But there would be time enough for that later. His immediate need was to get out. Already the food supply was running low, and his offspring was becoming enormous. He'd have to leave soon if he was ever going to. And he'd have to do something about his own growth. Already it was reaching dangerous levels. He was on the ragged edge of another reproduction, and he couldn't afford it. Regretfully, he began moving the cornified cells of his mantle and his under layer toward his inner surfaces, arranging them in a protective layer around his germ plasm and absorptive cells. There would be enough surface absorption to take care of his maintenance needs, and his body could retain its peak of cellular energy. Yet the desire to feed and bud was almost overpowering. His body screamed at him for denying it the right that food would give it, but Kworn resisted the demands of his flesh until the frantic cellular urges passed. Beside him his offspring pulsed with physical sensation. Kworn envied it even as he pitied it. The poor mindless thing could be used as a means to the end of his escape, but it was useless for anything else. It was far too large, and far too stupid, to survive in the outside world. Kworn extruded a net of hairlike pseudopods and swept the tank in which they lay. It was featureless, save for a hole where the filament had not completely withdrawn when it had pulled him into this place. A few places in the wall had a different texture than the others, probably the sense organs of the recorder. He rippled with satisfaction. There was a grille of poison metal in the top of the tank through which flowed a steady current of warm air. It would be pleasant to investigate this further, Kworn thought, but there was no time. His offspring had seen to that. He placed his eye on a thin pseudopod and thrust it through the hole in the wall of the tank. It was still night outside, but a faint line of brightness along the horizon indicated the coming of dawn. The artefact glittered icily beneath him, and he had a feeling of giddiness as he looked down the vertiginous drop to the disc below. The dark blotch of Caada's burned body was almost invisible against the faintly gleaming loom of the still-warm disc. Kworn shuddered. Caada hadn't deserved a death like that. Kworn looked down, estimating the chances with his new intelligence, and then slapped a thick communication fibril against his offspring's quivering flesh and hurled a projection at its recoiling mass.
