Fannia was frozen for a moment, unable to believe his eyes. Donnaught halted behind him. Natives were rushing forward by the hundreds now, their knives poised, screaming at the Earthmen.

The losers probably joined the victors; the tribe must have grown until it could take over the planet by sheer weight of numbers." Fannia looked carefully at Donnaught, trying to see if he understood. "It's anti-survival, of course;
