Then came the Partners.
Man and Partner could do together what Man could not do alone. Men had the intellect. Partners had the speed.
The Partners rode their tiny craft, no larger than footballs, outside the spaceships. They planoformed with the ships. They rode beside them in their six-pound craft ready to attack.
The tiny ships of the Partners were swift. Each carried a dozen pinlights, bombs no bigger than thimbles.
The pinlighters threw the Partners—quite literally threw—by means of mind-to-firing relays direct at the Dragons.
What seemed to be Dragons to the human mind appeared in the form of gigantic Rats in the minds of the Partners.
Out in the pitiless nothingness of space, the Partners' minds responded to an instinct as old as life. The Partners attacked, striking with a speed faster than Man's, going from attack to attack until the Rats or themselves were destroyed. Almost all the time, it was the Partners who won.
With the safety of the inter-stellar skip, skip, skip of the ships, commerce increased immensely, the population of all the colonies went up, and the demand for trained Partners increased.
Underhill and Woodley were a part of the third generation of pinlighters and yet, to them, it seemed as though their craft had endured forever.
