It had been days since had come to this hell. He was unsure of how many. When one lived as long as he time sometimes got away from one. Days, months, what did they matter but to measure sleep or plan an attack in darkness?
When he had set off to explore he'd eventually found a weak flashlight. It helped a bit. His night vision was not as it should have been either. It had always been marginally better than humans. Now, it was just another way he had been diminished.
When he first saw the giant window to the stars he had stood there, hand against the glass, for hours. It had driven reality home. He was really in the vast, unknown blackness. No soil, no green anywhere, most likely for unfathomable spans. It would account for his connection to his sister being gone. Such was never meant to endure such unimaginable distances.
The stars. He recognized none of the constellations, but why would he from a different angle and remoteness? From all he had heard the others were all from different times, different worlds. Different realities.
In some what he had long witnessed had come to pass. Humanity had greedily used up the world and went off to devour other ones. The realm of the unseen had passed.
He had made a perfunctory examination since then. He'd found living quarters where some of the others had settled themselves, and then found his own as far away as possible. In cleaning the place he had found a gold ring on the sink in the bathing room. It was the kind humans used to mark themselves married. They were sentimental of such things and he wondered why one had left this. He had also come across a infant's pacifier in a hallway.
He'd hears the soft scraping in the walls and on occasion sought sight of small movement in the shadows. Likely rats. Where vermin went other vermin followed.
In the poor light he had mapped the corridors, noting maintenance plates and testing doors.
He had found this treasure. It was as dusty as every other area which is why he was working now to clean it. The padded floor spoke of it's purpose, and the size was impressive enough to allow free range of techniques. He considered the mirrors foolish. Any decent use would shatter them. At least if there were made of common glass.
