Durham felt it, a subliminal feeling without any reason to it, like the sadness of a summer night or of birth and laughter or of gull's wings white and swift against the sky. The Star shone, palely, gently. He tried to see if it was round or any other shape, if it was solid or vaporous, but he could not see anything but that soft shining, like mist around a winter moon.
Durham shook himself and wondered why, when he was already so sure of death, he should be so afraid. "All right," he said. "How is it freed?"
"The darkbirds do that. Watch."
He spoke to them, one word, and in the glass-walled prison there was a stirring and a swirling of shadows around the soft shining of the Star. Durham saw a disc set in the metal overhead. One of the darkbirds touched it. There was an intense blue flare of light, and Durham felt the throbbing of hidden dynamos, a secret surge of power. The glass walls darkened and grew dim, the low roof turned and opened to the sky. And through the barrier window, Durham watched the waking of a star.
He saw the frosty shining brighten and spread out in slow unfurling veils. There was a moment when the whole building seemed filled with moonfire as cold as the breath of outer space and as beautiful as the face of a dream, and then it was gone, and the darkbirds were gone with it.
"Come on," said Karlovic, a harsh incongruous voice in the stunned darkness that was left behind, and Durham came, up the ramp and out into the parklike space beyond, and all the tall lichens were standing dead and sheathed in ice.
High above, burning cold over the city, a new star shone.
They followed it, through a silence as deep as the end of the world. Everything had taken cover at the rising of that star, and only the two men moved, the thermal units of their suits turned on high, through streets all glazed with ice and cluttered here and there with the wreckage and the dead of the rioting. The darkbirds were forcing the Star to stay high, but even so nothing could live long without protection in that sudden, terrible winter.
The road to the port lay blank and bare. They found one of the smaller vehicles, its driver dead beside it. Karlovic got it going, moving the great levers with Durham's help. After that they rushed faster through the empty night. Durham shut his eyes, thinking.
He opened them, and the spaceport of Senya Dik lay black and deserted around him, and Karlovic was gasping to him for help. Together they pulled down the lever that stopped their conveyance. They scrambled down and ran out toward the small lifeboat, slipping and stumbling, dying inside their suits. They fell into the airlock, and Durham slammed the door and spun the wheel, waiting out the agonizing seconds while the tiny chamber cleared and then refilled, and they could tear off their helmets and breathe again. They looked at each other and laughed, and hugged each other, and laughed again, and then went in to the cabin.
