The rock fell to the ground. The gun paused, then resumed its calm swivel, its slow circling.
"You see," Dorle said, "it noticed the rock, as soon as I threw it up in the air. It's alert to anything that flies or moves above the ground level. Probably it detected us as soon as we entered the gravitational field of the planet. It probably had a bead on us from the start. We don't have a chance. It knows all about the ship. It's just waiting for us to take off again."
"I understand about the rock," Nasha said, nodding. "The gun noticed it, but not us, since we're on the ground, not above. It's only designed to combat objects in the sky. The ship is safe until it takes off again, then the end will come."
"But what's this gun for?" Tance put in. "There's no one alive here. Everyone is dead."
"It's a machine," Dorle said. "A machine that was made to do a job. And it's doing the job. How it survived the blast I don't know. On it goes, waiting for the enemy. Probably they came by air in some sort of projectiles."
"The enemy," Nasha said. "Their own race. It is hard to believe that they really bombed themselves, fired at themselves."
"Well, it's over with. Except right here, where we're standing. This one gun, still alert, ready to kill. It'll go on until it wears out."
"And by that time we'll be dead," Nasha said bitterly.
"There must have been hundreds of guns like this," Dorle murmured. "They must have been used to the sight, guns, weapons, uniforms. Probably they accepted it as a natural thing, part of their lives, like eating and sleeping. An institution, like the church and the state. Men trained to fight, to lead armies, a regular profession. Honored, respected."
