The Nipe squatted, brooding, in his underground nest, waiting for the special crystallization process to take place in the sodium-gold alloy that was forming in the reactor.

How long? he wondered. He was not thinking of the crystallization reaction; he knew the timing of that to the fraction of a second. His dark thoughts were focused inwardly, upon himself.

How long would it be before he would be able to construct the communicator that would put him in touch with his own race again? How long before he could discourse again with reasonable beings? For how much longer would he be stranded on an insane planet, surrounded by degraded, insane beings?

The work was going incredibly slowly. He had known at the beginning that his knowledge of the basic arts required to build a communicator was incomplete, but he had not realized just how painfully inadequate it was. Time after time, his instruments had simply refused to function because of some basic flaw in their manufacture—some flaw that an expert in that field could have pointed out at once. Time after time, equipment had had to be rebuilt almost from the beginning. And, time after time, only cut-and-try methods were available for correcting his errors.

Not even his prodigious and accurate memory could hold all the information that was necessary for the work, and there were no reference tapes available, of course.

He had long since given up any attempt to understand the functioning of the mad pseudo-civilization that surrounded him. He was quite certain that the beings he had seen could not possibly be the real rulers of this society, but he had, as yet, no inkling as to who the real rulers were.

As to where they were, that question seemed a little easier to answer. It was highly probable that they were out in space, on the asteriods that his instruments had detected as he had dropped in toward this planet so many years before. He had made an error back then in not landing in the Belt, but at no time since had he experienced the emotion of regret or wished he had done differently; both thoughts would have been incomprehensible to the Nipe. He had made an error; the circumstances had been checked and noted; he would not make that error again.

What further action could be taken by a logical mind?

None. The past was unchangeable. It existed only as a memory in his own mind, and there was no way to change that indelible record, even had he wished to do such an insane thing.

Surely, he thought, the real rulers must know of his existence. He had tried, by his every action, to show that he was a reasoning, intelligent, and civilized being. Why had they taken no action?

His hypotheses, he realized, were weak because of lack of data. He could only wait for more information.

That—and continue to work.
