Evening light slowly poured in through the dirty windows of the old factory. Coal Street had been haunted by emptiness and broken windows for years, but for Lena it was the perfect place to wander after school. She was seventeen years old and it was a poignant feeling that the world as everyone knew it wasn't enough - that somewhere around the corner something else was hiding. That Saturday, as the hot summer was fading into oblivion, her friend Max suggested they go inside the largest of the factory halls. "I've always been scared," he said, glancing at the tall, rusty door. "But today I think I'm ready." Lena smiled just slightly, as if she had been waiting for this moment for a long time. They crossed the threshold. Inside, the smell of rust mingled with the aroma of rain that had entered through the roof. Faded conveyor belts wriggled like snakes across the concrete floor, and the walls were almost entirely covered with collages of graffiti - some looked like real characters, others like abstract creatures that could not be named. Lena stopped at one of the murals - a girl made of glass, with the entire universe shining through. "I always thought these paintings were created out of nothing," she muttered, more to herself than to Max. Suddenly something at the door slammed with a clatter. They both looked in that direction nervously, but saw nothing. Instead, Lena got the impression that the graffiti had started to vibrate, as if a current was flowing between their contours. Max took out his phone, but the screen remained black. "No reception... Nor light. I wonder. Let's go on," he suggested, although anxiety could be heard in his voice. The deeper they went in, the more the surroundings seemed to change. The old machines were beginning to look like fantastic vehicles, and the light reflected off them in colours Lena couldn't name. Behind one of the pillars, she spotted a shadow - it was the outline of a figure, but too fuzzy to tell if it was a person or simply a play of light and imagination. As they took a few more steps, Lena heard a quiet whisper. "Did you hear that?" she asked, squeezing Max's hand. "I think... yes," he replied, looking at her with wide eyes. Suddenly, the glare of the torch Lena was holding fell on the mural, which had looked very different a moment ago. It now showed a door where abstract patterns had previously been painted. The door had a handle that looked almost real, as if it protruded beyond the wall. Lena felt her pulse quicken. Everything seemed possible in that moment. She walked over to the wall, reached out and touched the handle, which surprisingly was cool and metal. For a second she thought it was just a play of light and her imagination, but the door moved under her touch, opening slowly with a deafening creak.... Behind them stretched a space she could not describe in any words she knew. However, before Lena had time to take a step, she heard a rustling and quiet breathing from behind her, as if someone - or something - was watching them from behind. Lena looked at Max, he looked at her, and then they both turned their gaze towards the depths of the open door. Who or what was waiting for them there?
