Poznań, early September. The air was still saturated with the memory of summer, although the leaves on the Warta River were already turning yellow. Maja, Igor, Lena and Oskar sat on the wall of the old amphitheatre, which in summer holidays used to be their refuge from the adult world and, at the same time, the laboratory of their dreams. This year they were eighteen and everything seemed different - even the air. - 'Come on, Lena, say it,' muttered Maja, glancing at the watch on her phone. - 'We've only got an hour until tutoring before I get home. Lena, the quietest of the four, moved the tip of her shoe along the wall. - Sometimes I feel like... I don't belong in this town. Like there's something more in me. Something I'm afraid to fully touch. Oskar raised his eyebrows. - 'Cool you guys, I feel like I'm not going to make it through these matriculations.' - He laughed, but it didn't sound entirely sincere. Igor took his eyes off the drawing he was sketching in his notebook. The city under his pencil was dense, full of fog and tall towers. - 'I sometimes have the feeling,' he said slowly, 'that I can hear people's thoughts when I try very hard. Silence fell for a moment. A tram passed in the distance; its metallic sound echoed among the empty benches. - Are you serious? - Maja asked. - Because I... At that moment her phone rang. She looked at the screen, but the number was unfamiliar, only four digits pulsed on the display: 1701. She answered, hesitating for a fraction of a second. - Hello? For a moment, all she heard was a noise, as if someone was whispering right next to her ear. Then a deep voice rang out: - Maja, you need to be careful. You are not alone. They know. The connection was cut off. Maja stared at the blank screen, her fingers trembling more than she cared to show. - What happened? - Asked Igor, slipping his hand into his sweatshirt pocket. Maja slowly recounted the strange phone call. Lena became more serious. - Do you think someone is watching us? Oskar turned suddenly, instinctively, as if he had indeed spotted someone in the thickening twilight. In the light of the lantern, something moved in the shadows under the pillar of the amphitheatre. For a moment, the four friends had the feeling that they were no longer alone. Then Lena felt a wave of energy inside her. One that she didn't know how to name. She felt like running towards the shadows, even though everything inside her screamed against danger. Igor closed his eyes - and saw images that could not belong to him: blackness streaming across the cobblestones, the light of flickering eyes, fingers sliding across the screen of a phone with a four-digit code. They were all silent, each gripped by their own anxiety. As the shadow beneath the pillar trembled and something - or someone - slid out of the lantern light, Maja felt her heart beat faster than usual. A tension hung in the air that made a chill seep through them all. What was really waiting for them on the other side of the ordinary? Will they decide to use their powers, and if so, for what? In that moment, as the fates of their friends began to become intertwined with something bigger, their world was no longer safe.
