Their intelligence was surprising and they seemed to be partially receptive to human thoughts, as Bill Humbolt had written. By the end of the fifteenth year their training had reached such a stage of perfection that a mocker would transmit or not transmit with only the unspoken thought of its master to tell it which it should be. In addition, they would transmit the message to whichever mocker their master’s thought directed. Presumably all mockers received the message but only the mocker to whom it was addressed would repeat it aloud.

They had their method of communication. They had their automatic crossbows for quick, close fighting, and their long range longbows. They were fully adapted to the 1.5 gravity and their reflexes were almost like those of prowlers⁠—Ragnarok had long ago separated the quick from the dead.

There were eight hundred and nineteen of them that year, in the early spring of one hundred and fifty, and they were ready and impatient for the coming of the Gerns.

Then the transmitter, which had been in operation again for many years, failed one day.
