Nila had always told herself that her home Lake Lira was the most ordinary place on earth. It lay on the edge of the old town, surrounded by a dense evergreen forest where her wildest imaginings had been awakened since childhood. But something different was happening over Lyra this summer. A mysterious mist drifted over the water even on the warmest days, and locals told of seeing strange shadows in it. One night Nila, unable to sleep, slipped out of the house, intrigued by the whispers she had begun to hear since the mist had appeared over the lake. The seventeen-year-old girl was already used to rumours of ghosts, but this evening the sounds seemed more real than ever. Leo, her best friend, was waiting for her by the shore, although he too was paler than usual. - Did you hear that? - She whispered, looking out at the lazily dancing waves. Leo nodded his head. - 'Those voices... They spoke to me by name. Once I even saw my own reflection smiling at me, though I was serious myself. In the silence, broken only by the splash of invisible fish, Nila felt an icy shiver run down her spine. For a moment they were both silent, gazing at the white glow floating above the water. Suddenly, the mist thickened, as if something - or someone - was trying to break through it. A ragged laughter sounded from the depths of the lake and two silhouettes clarified by the shore itself. Their eyes shone with a blue light and their voices sounded simultaneously familiar and alien. - Nila, Leo... - rang out in the darkness. - We have been waiting for you. A fortuitous gust of wind revealed the hidden ruins of an old tower under the water, the existence of which they knew only from legends. Nila squeezed Leo's hand tighter and trembled. The mystery was closer than ever, and the answer was at hand. Only were they ready to know it?
