The wind hummed a gentle Christmas lullaby as thick, swirling fog rolled over the rooftops. Inside his cosy bedroom, Leo was still wide awake. The night was hushed, but his heart was dancing with festive excitement.

Beside his bed, Leo’s favourite star-shaped night-light cast a warm, golden glow across the room. It was a comforting, steady light that always made him feel brave and ready for any adventure, even on the quietest, darkest nights.

Suddenly, a soft sound drifted through the frosty air. Jingle, jangle, chime! It was the unmistakable, musical ring of sleigh bells, echoing softly through the misty night.

Leo sat up straight, his ears tingling. He crept over to the window and pressed his nose against the cool glass. Outside, the world was wrapped in a thick blanket of grey fog, hiding the stars and the moon from view.
