Lena and Antek were siblings who loved to play together at their grandmother's house. One rainy afternoon they got bored with all the games and it was impossible to go outside. Then grandma said with a smile: "Why don't you look in the attic? There are lots of old things there for you to look at." The children ran up the wooden stairs to the top. The attic smelled of dust and old books. There were lots of boxes, trunks and.... a huge wooden wardrobe, very different from all the others. It had gold knobs in the shape of lions and intricately carved doors. - Come, let's have a look inside - Antek suggested, and Lena nodded eagerly. As soon as they opened the door, a light breeze blew from inside the wardrobe, which smelled like a forest just after the rain. Inside, instead of shelves, they saw a wall with hundreds of tiny, glowing stars. There was also soft, emerald grass and.... something that looked like a luminous tunnel, leading deep into the wardrobe! - Can you see it, Lena? - Antek asked in a whisper. - Yes, do you think we can go in there? Suddenly a quiet light came to them from the depths of the tunnel, which began to pulsate and attract their eyes. Lena took the first step, Antek grabbed her hand and together they slowly walked inside. Behind them, the wardrobe door slammed quietly. Before them appeared an unfamiliar world full of colours and sounds like they had never seen before. Coloured lights flashed in the distance and a mysterious shadow moved between the silvery trees. Lena and Antek looked after each other, wondering what was going to happen now....
