“As you all recall, I hope, the phenomenon below us, the Shield, is the direct result of the Old Empire-Terran Wars of ages ago. At that time, the inhabitants of this planet first broke free of their own system and started to come out to the stars.
“They found there a multiracial empire nominally ruled by a race known to us as the Veen. The Terrans were invited to join the empire, accruing the same rights and privileges as had historically been granted to all new space-going races for thousands and thousands of years.”
“And they refused,” put in Rappan. “Yes, they refused. It became quickly apparent to the Veen that the Terrans intended to carve out a little pocket empire of their own in another sector of space. Since Terra was so far away from the center of things, so to speak, the Veen decided that for the sake of peace—and the Veen—this could not be allowed to take place. Accordingly, there was a war, or rather, a series of wars. These lasted for centuries, despite the overwhelming numerical superiority of the Veen. Gradually, the Terrans were pushed back to their own home world. A standoff ensued, as the Veen and .their

allies were unable to break the ultimate defenses of the Terrans.
“Then a great scientist of one of the allied races of the Veen discovered, quite by accident, the quasi-mathematical principle behind the Shield. The nature of the Shield forbade its use on anything smaller than a good-sized moon. It was thus useless for such obvious military applications as, for example, a ship defensive screen. Then someone got the bright idea of enveloping the entire planet of Terra in one huge Shield, making it into an impenetrable cage. At worst, it would provide the Empire with a breathing spell in which to marshal its sorely battered forces. At best it would restrict the Terrans to their own fortress until such time as the Veen saw fit to let them out. The chances of the Terrans accidentally stumbling onto the same principle was considered to be slight. As you can now see, this indeed has been the case.” The Professor sighed again, a high, whistling sound.
