Krein gave a yawn as he stood from his crouched position, his shoes now back firmly on his feet, several piles of items before him. One of pipes and poles, rusted, of course, another of miscellaneous fabrics and cloths, dust covered and with potential mold on them. Several piles of nuts, bolts, and screws, all rusted and potentially useless, although he was a bit concerned as to how many, if any, of these bolts and screws actually came off of the building itself. The night was approaching, and along with it the drop in temperature, perhaps it was time to pick room for himself to sleep in. He threw a large, thick, sheet of fabric that he had found over his shoulder, a cover for his den, should he find one. He didn't really like small spaces, but he knew that for sleeping a small shelter with this fabric covering it would make it warm enough for him. Although for a room he would like something a bit more open, perhaps one that has a large support beam in the middle with a multitude of other beams branching off it, like a giant metal tree. He would also like the floor to be covered with large poles or pipes that he could snake and crawl through, or hide within if need be, which would also save him the time of having to create his sleeping area himself.
After searching through several potential rooms, he found one towards the end of the building that suited his needs, it wasn't exactly what he wanted, but it was closer than any of the other rooms he had been in. It also had some windows that faced the east, meaning the sun would shine in with its warmth once it started to rise. As a bit of added luck there was a nice pile of pipes and other assorted junk that seemed for form a nice, small, den practically right under the window. This room felt homey already, he simply spread the sheet atop it, and anchored it to the ground by placing some heavy stones at the corners, the rest of the room would be fine as is.
"I wonder when the rest will arrive," he asked himself, he left the room he had chosen and went back to the room with the main entrance, once again climbing up to the ceiling, through the hole, and out another hole in the room. He sat atop the roof, looking out in the direction of the entrance, waiting for everyone's arrival.
