Again there was the awful pressure, the crushing weight. Violent forces shook the ship. Andra moaned softly. Strange words issued from her lips. Then they were out of the clutch of the awful force. "Landing at Nobla," Ven said. Panels slid away and Karn could see through the walls of the ship. Below them was a city. They dropped toward it and its gargoyle-topped towers reached up to meet them. Strange birds winged across an azure sky. They came down over the city and landed gently in a meadow next to the mouth of a great cavern. * * * * * "Nobody around," Ven said. "I don't understand it." "They weren't expecting us to land at Nobla," Andra said. "You're always worrying about something. Come on, let's get out." The ramp came down and the four descended, Harus leading the way. Karn wondered why they moved so warily. This was their own land. What were they afraid of? To one side the mouth of the cavern yawned dark and forbidding as they went toward it. Andra explained to Karn that it was the mouth of a tunnel which led to the city proper. There were walls about the city which were never opened. They were almost to the tunnel when the green things came at them. Slimy beings, as tall as Harus and Ven, covered with green scales and four-armed, more lizards than men, they poured from the tunnel. Emitting bird-like cries they swarmed forward, long spears pointing ahead at waist level. With a scream of fear, Ven spun around and ran. Andra and Harus stood petrified. Their reactions were typical, apparently, for the Green Ones came on as though used to encountering little resistance. Even the sight of Karn, huge of frame and heavy-thewed, draped in his wolfskin, failed to register. It was a fatal mistake. As the first of the Green Ones reached him Karn side-stepped nimbly, sweeping the spear aside and tearing it from its bearer's grasp. Karn's other hand shot out and connected with a snout. The man-lizard dropped, its face turned to green and oozing pulp. In Karn's hands the spear became a club. The Green Ones turned toward him in a body, trying to fend off this unexpected attack. They were met by a whirling staff that crushed whatever it hit. Karn's power was overwhelming. His rush cut a swath of death through the green ranks, forcing them back. He heard Andra calling and looked back over his shoulder. She was standing at the opening in the ship, screaming to him. In their blind fear, Harus and Ven were prepared to take off and leave him behind. No saber-tooth could have altered the direction of his charge more quickly than Karn. Before the Green Ones could even attempt to block his retreat, Karn was through them and past them. * * * * * Harus and Ven sprawled in their flight chairs, panting as though it were they who had done the fighting. Only Karn seemed relaxed as the ship rose and hovered above the Green Ones.
