The Moon Sept waited for twilight in a ring about the shattered clearing in which the invaders were halted. The pain that had slashed through every member of the sept at the initial explosion was literally beyond comparison: when agony gouged at the Tree, the brothers had collapsed wherever they stood, spewing waste and the contents of their stomach uncontrollably. Hours later the second blast tore away ten separate trunks and brought down a hectare of canopy. The huge silver beasts had shoved the debris to the side before they settled down in the new clearing. That explosion was bearable on top of the first only because of the black rage of the Mothers now insulating the Moon Sept from full empathy with their Tree; but not even the Mothers could accept further punishment at that level. Hilf moaned in the root-alcove, only dimly aware that he had befouled it in reaction. He was a conduit now, not the Caller in fact, for the eyeless ones had assumed control. The Mothers had made a two-dimensional observation which the males, to whom up and down were more important than horizontal direction, had missed: the invaders were proceeding toward the Nest. They must be stopped.
The full thousand of the Moon Sept blended into the leaves with a perfection achieved in the days in which there had been carnivores in the forest. When one of the Folk moved it was to ease cramps out of a muscle or to catch the sun-pearl on the delicate edge of a claw. They did not forage; the wracking horror of the explosions had left them beyond desire for food.
The effect on the Tree had been even worse. In multi-kilometer circles from both blast sites the wood sagged sapless and foliage curled around its stems. The powerguns alone had been devastating to the Tree's careful stasis, bolts that shattered the trunks they clipped and left the splinters ablaze in the rain. Only the lightning could compare in destructiveness, and the charges building in the uppermost branches gave warning enough for the Tree to minimize lightning damage.
There would be a further rain of cyan charges, but that could not be helped. The Mothers were willing to sacrifice to necessity, even a Tree or a sept.
The four silvery beasts lay nose to tail among the craters, only fifty meters from the standing trunks in which the Folk waited. Hilf watched from a thousand angles. Only the rotating cones on the foreheads of each of the beasts seemed to be moving. Their riders were restive, however, calling to one another in low voices whose alien nature could not disguise their tension. The sun that had moments before been a spreading blob on the western horizon was now gone; invisible through the clouds but a presence felt by the Folk, the fixed Moon now ruled the sky alone. It was the hour of the Moon Sept, and the command of the Mothers was the loosing of a blood-mad dog to kill.
"Death!" screamed the sept-brothers as they sprang into the clearing.
There was death in plenty awaiting them.
The antipersonnel strips of the cars were live. Hilf was with the first body when it hurtled to within twenty meters of a car and the strips began to fire on radar command. Each of the white flashes that slammed and glared from just above the ground-effect curtains was fanning out a handful of tetrahedral pellets. Where the energy released by the powerguns blasted flesh into mist and jelly, the projectiles ripped like scythes over a wide area. Then the forest blazed as flickering cyan hosed across it.
The last antipersonnel charge went off, leaving screams and the thump of powerguns that were almost silence after the rattling crescendo of explosions.
The sept, the surprising hundreds whom the shock had paralyzed but not slain, surged forward again. The three-limbed Caller of the invaders shouted orders while he fired. The huge silver beasts howled and spun end for end even as Hilf's brothers began to leap aboard—then the port antipersonnel strips cut loose in a point-blank broadside. For those above the plane of the discharges there was a brief flurry of claws aimed at neck joints and gun muzzles tight against flesh as they fired. Then a grenade, dropped or jarred from a container, went off in the blood-slick compartment of number one car. Mingled limbs erupted. The sides blew out and the bins of ready ammunition gang-fired in a fury of light and gobbets of molten iridium.
The attack was over. The Mothers had made the instant assumption that the third explosion would be on the order of the two previous—and blocked their minds off from a Tree-empathy that might have been lethal. Without their inexorable thrusting, the scatter of sept-brothers fled like grubs from the sun. They had fought with the savagery of their remote ancestors eliminating the great Folk-devouring serpents from the forest.
And it had not been enough.
