The rain was pounding hard on the windowsills of the old library as Leon once again crossed its threshold. The café in the market square was full of noise, and he was just looking for silence, enough to collect his thoughts. Lately, he had been feeling as if the world around him was changing faster than he was - or was it him who was moving away? A tall bookcase, covered in dust, caught his attention. Behind it, barely visible, led a staircase that none of the librarians had ever mentioned. Leon, surprisingly, did not hesitate - curiosity worked stronger than reason. The stairs creaked underfoot, and then he was engulfed by the darkness of the corridor, in which there was absolutely no light except the faint glow of the telephone. At the end of the corridor was a door - a tall door covered in alternating frosted and shiny glass. When he swung it open, he froze. On the other side lurked a seemingly different library, lit by the glow of lamps, where dozens of mirrors covered the walls. They reflected not only Leon's image, but also other figures - a young girl in a cloak and a tall boy with a strangely shiny bracelet. "They can see you," whispered the girl from behind him. Leon turned abruptly, but no one was there. Only the echo of his own footsteps spread through the room full of mirrors. In each of them he saw himself in a different guise: once older, once younger, sometimes with a scar leveled vertically across his cheek. - 'We're late,' said a boy's voice suddenly. Leon felt someone grab his arm and pull him through one of the mirrored portals. The world around him blurred for a brief moment, and when everything calmed down, he was standing in the middle of a square full of people who seemed to come from other eras, with a huge, silvery structure hovering above them - a huge pendulum, reflecting light in all directions. - 'If we don't make it before midnight, all will be lost,' whispered the girl with the cloak, looking Leon straight in the eye. At the same moment, the pendulum stopped and an icy breeze ran across the square. Leon didn't know whether he should take a step forward, or perhaps run back through the mirror. Anything could have happened.
