Christmas Eve smelled of cinnamon and the snow danced outside the window. Lena was tweaking the lights on the Christmas tree while Antek was adding a paper chain. Carols played quietly in the living room, although everyone was bustling around in the kitchen. A star glistened on the top of the tree, as if twinkling. Lena smirked with pride and took a step back. Suddenly, one bauble moved slightly on the lower branch. Lena froze and looked under the Christmas tree, searching for the cause. The cat was asleep under the armchair, so it wasn't him. Antek raised his eyebrows and whispered: "Do you see it now?" The bauble moved another bit and disappeared into the thick needles. A soft sound came from above, like a bell hidden in a cloud. Then they heard a whisper, soft and clear: "Leno.... Antek..." They glimpsed the staircase leading to the attic, dark as a tunnel. Tiny ice crumbs glistened on the steps, like the footprint of an unseen visitor. Lena grabbed a torch from a drawer and nodded at her brother. They carefully climbed up, being careful of the creaking boards. The door to the attic was ajar, although no one had opened it today. Beyond the threshold, the air was cold and smelled of snow and cedar. In the middle stood an old chest with a star engraved on the lid. The lock shimmered silvery, as if it was waiting just for them. Antek squeezed Lena's hand and whispered: "Maybe it's a gift? Or a trap?" The lock clicked of its own accord, the lid vibrated, and a pale, moving light spilled from within.
