"Landed at last, five hours ago. (Expletive) what a mess! The landscape below as we came in on the (approach run?) was glowing red in places all around Seltar for miles. There were lakes of molten rock, bright orange, some with walls of rocks plunging straight into them where whole mountains have been blown away. The base is covered deep in dust, and some of the surface installations have been crushed by flying debris. The defenses are holding out, but the outer perimeter is (torn to shreds?). Most important—[unreadable] diameter dish of the Annihilator is intact and it is operational. The last group of ships in our flight was wiped out by an enemy strike coming in from deep space. Koriel has been collecting on all sides."

Hunt laid the paper down and looked at Maddson. "Don," he said, "how much have you been able to piece together about this Annihilator thing?"

"It was a kind of superweapon. There was more information in some of the other texts. Both sides had them, sited on Minerva itself and, from what you're reading right now, on Luna too." He added as an afterthought, "Maybe on other places as well."

"Why on Luna? Any ideas?"

"Our guess is that the Cerians and the Lambians must have developed space-flight technology further than we thought," Maddson said. "Perhaps both sides had selected Earth as their target destination for the big move, and they both sent advance parties to Luna to set up a bridgehead and . . . protect the investment."

"Why not on Earth itself, then?"

"I dunno."

"Let's stick with it for now, anyway," Hunt said. "How much do we know about what these Annihilators were?"

"From the description dish, apparently it was some kind of radiation projector. From other clues, they fired a high-energy photon beam probably produced by intense matter-antimatter reaction. If so, the term Annihilator is particularly apt; it carries a double meaning."

"Okay." Hunt nodded. "That's what I thought. Now it goes silly." He consulted his notes. "Day Nine they were getting organized and repairing battle damage. What about Day Ten, then, eh?" He resumed reading:

"Day Ten. Annihilator used for the first time today. Three fifteen-minute blasts aimed at Calvares, Paneris, and Sellidorn. Now, they're all Lambian cities, right?

"So they have this Annihilator emplacement, sitting on our Moon, happily picking off cities on the surface of Minerva?"

"Looks like it," Maddson agreed. He didn't look very happy.
