"That's the way they put down Alien-science in the other rising, long ago. A chief's a chief. He's got more in common with another chief--even a chief of Strangers--than with his own people. You attack Ancestor-science, and you're attacking their power as chiefs. They'll work together then. They'll give each other men, weapons, information. They'll do everything they can against the common enemy. Against the only people who really want to hit back at the Monsters. I should have remembered! Damn it all," the Trap-Smasher groaned through his ruined mouth, "I saw that the chief and Ottilie were suspicious. I should have realized how they were going to handle it. They were going to call in Strangers, exchange information--and unite against us!" Eric stared at his uncle, dimly understanding. Just as there was a secret organization of Alien-sciencers that cut across tribal boundaries, so there was a tacit, rarely-used understanding among the chiefs, based on the Ancestor-science religion that was the main prop of their power. _And_ the power of the leaders of the Female Society, come to think of it. All special privileges were derived from their knowledge of Ancestor-science. Take that away from them, and they'd be ordinary women with no more magical abilities than was necessary to tell edible food from Monster poison. Grunting with pain, Thomas the Trap-Smasher wormed his way up to a sitting position against the wall. He kept shaking his head as if to jar recollection loose. "They came up to us," he said heavily, "Stephen the Strong-Armed and his band came up to us just after you'd gone into Monster territory. A band from Mankind with a message from the chief--who suspected anything? They might be coming to tell us that the home burrows were under attack by Strangers. Strangers!" He gave a barking laugh, and some blood splashed out of his mouth. "They had Strangers with them, hidden all the way behind in the corridors. Mobs and mobs of Strangers." * * * * * Eric began to visualize what had happened. "Then, when they were among us, when most of us had reslung our spears, they hit us. Eric, they hit us real good. They had us so much by surprise that they didn't even need outside help. I don't think there was much left of us by the time the Strangers came running up. I was down, fighting with my bare hands, and so was the rest of the band. The Strangers did the mopping up. I didn't see most of it. Somebody handed me one hell of a wallop--I never expected to wake up alive." His voice got even lower and huskier. "I'd have been lucky not to."
