Loki closed the door behind them and waited for his eyes to adjust to the dim glow of the streetlamps that came in through the windows. Within the klaxon was much louder, and it sent a shiver of unease down his spine. That was the kind of sound meant to call others to investigate a disturbance. They shouldn't linger, even if they could turn it off.
And he certainly didn't know how to do that. He wasn't even sure where the noise was coming from. It seemed to fill the room like a physical presence, and he had to yell to be heard through the din. "If you know how, it sounds like a fine idea!" he howled at her, glancing around the darkened enclosure. "But I..."
The sound that interrupted him was not from the same source as the klaxon. It was most likely not even the first of its kind, just the first to be loud enough that they could hear it. He could best describe it as a metallic thud, and as he spun to seek it source, a beam of light came from the giant metal door that took up the wall next to where they had entered. The light was coming through a hole... which had just been punched by the point of a tail as big as a good-sized dog. The drip of venom that fell from the tail's tip as it exited the hole froze Loki in fear, and then sent him hurtling across the building, looking for another way out.
