Huddled at their last retreat the Rell watched the ever smaller ice cap annually diminish and lived with the knowledge they faced extinction. A mere thousand years [88]  more would see even this trifling remainder gone.

Oh, you might say there was hope … of a sort. There might be Rell in the northern hemisphere. The canals girdled the globe and a similar ice cap could well exist at the opposite pole. Rell perhaps survived there also.

But this was scant comfort. The fate of the Rell in the South was sealed. What hope of any brighter future for those in the North? And if they survived a few hundred thousand years longer … or if they had perished a similar period earlier, what actual difference did it make?

There was no one more aware of this gloomy future than Raeillo/ee13.

In the old days a single unit of the group-mind of the Rell would have possessed but a single function and exercised this function perhaps a dozen times during his life. But due to the inexorable shrinkage only the most important problems now could command mind-action and each unit had been forced to forsake specialization for multi-purpose endeavors.

Thus Raeillo/ee13 and his mate Raellu//2 were two of the five thousand units whose task was to multiply in any group-mind action involving mathematical prediction. Naturally Raeillo/ee13 and Raellu//2 did not waste their abilities in mundane problems not involving prediction. Nor did they divide, add, or subtract. That was assigned to other units just as several million of the upper groups had the task of sorting and interpreting their results. Raeillo/ee13 and Raellu//2 multiplied only. And it must be admitted they did it very well. It is a pity the Rell could not have multiplied physically as easily as Raeillo/ee13 and Raellu//2 multiplied mentally.

With the exception of an occasional comet or meteor the Rell were seldom diverted by anything of a physical nature. The ice cap was their sole concern.

But one afternoon a rare physical phenomenon was reported by a bank of observer Rell.
