The familiar hiss of the airlock closing always brought a certain calm to Elias. He checked the readouts: pressure nominal, oxygen cycling. Outside the viewport, the void pressed in, speckled with the indifferent glow of distant stars. He’d done this thousands of times. Yet, tonight, a faint tremor ran through his hands as he ran them over the cold metal of the console. They had arrived.

He watched the primary monitor, a grid of flickering green squares representing the external sensors. A new cluster of lights had appeared, not on the celestial map, but within the orbital range. Their silhouette, stark against the galactic backdrop, grew steadily. He tightened his grip on the armrest. It was time.

The alarm, a low, persistent thrum, began. 'Intruder alert,' a synthesized voice announced, devoid of panic. Elias ignored it. His gaze was fixed on the screen, on the approaching forms. They were unlike anything he'd seen in the vast libraries of known designs. Smooth, dark, and utterly silent. He felt a primal dread, a chilling certainty that the end was near.

He pulled a small, silver locket from beneath his uniform, its surface warm from his skin. Inside, a miniature photograph of a woman and a child, smiling. A pang of longing, sharp and immediate. He looked up at the main viewscreen, where the lead vessel now dominated the frame. Its massive hull, perfectly symmetrical, reflected no light, absorbing it all.

Then, the soft chime. A data packet had arrived. He opened it, his heart pounding against his ribs. The message was brief, a single line of unfamiliar symbols. But beneath it, a smaller text, automatically translated.

Elias stared at the words, then at the approaching ships. A profound peace settled over him.

He pressed the activate button on his console. The station shuddered, a soft hum growing in intensity. The external lights, which had been off, flared to life, illuminating the vast, silent hanger where hundreds of smaller craft waited. Each one, meticulously maintained, was identical. He looked at the locket again, a slight smile touching his lips. It was true, then. They had finally come for them. He had done his job.
