Ulv had no compunctions about killing, only his darts couldn't penetrate the magter's thick clothing. As the magter turned, Ulv's breath pulsed once and death stung the back of the other man's hand. He collapsed into a crumpled heap. "Don't shoot," a voice called from outside the cave, and a man stepped through the swirling dust and smoke to stand in the beam from the light. Brion clutched wildly at Ulv's arm, dragging the blowgun from the Disan's mouth. The man in the light wore a protective helmet, thick boots and a pouch-hung uniform. He was a Nyjorder. The realization was almost impossible to accept. Brion had heard the bombs fall. Yet the Nyjord soldier was here. The two facts couldn't be accepted together. "Would you keep a hold on his arm, sir, just in case," the soldier said, glancing warily at Ulv's blowpipe. "I know what those darts can do." He pulled a microphone from one of his pockets and spoke into it. More soldiers crowded into the cave, and Professor-Commander Krafft came in behind them. He looked strangely out of keeping in the dusty combat uniform. The gun was even more incongruous in his blue-veined hand. After giving the pistol to the nearest soldier with an air of relief, he stumbled quickly over to Brion and took his hand. "It is a profound and sincere pleasure to meet you in person," he said. "And your friend Ulv as well." "Would you kindly explain what is going on?" Brion said thickly. He was obsessed by the strange feeling that none of this could possibly be happening. "We will always remember you as the man who saved us from ourselves," Krafft said, once again the professor instead of the commander. "What Brion wants are facts, Grandpa, not speeches," Hys said. The bent form of the leader of the rebel Nyjord army pushed through the crowd of taller men until he stood next to Krafft. "Simply stated, Brion, your plan succeeded. Krafft relayed your message to me--and as soon as I heard it I turned back and met him on his ship. I'm sorry that Telt's dead--but he found what we were looking for. I couldn't ignore his report of radioactive traces. Your girl friend arrived with the hacked-up corpse at the same time I did, and we all took a long look at the green leech in its skull. Her explanation of what it is made significant sense. We were already carrying out landings when we had your call about something having been stored in the magter tower. After that it was just a matter of following tracks--and the transmitter you planted." "But the explosions at midnight?" Brion broke in. "I heard them!"
