The world, having listened, now answered.
The first answer was not a word, but a change in the light.
The sun, which had been a constant, unwavering presence, began to dip below the horizon, painting the sky in hues of orange and purple.
It was the world’s first sunset, a silent, beautiful reply to the song that had filled it.
The first dweller, watching from the grove, felt a sense of peace it had never known before.
The first echo, its rhythmic pulse now a soft, steady heartbeat in the twilight, felt a sense of rightness, of a question asked and an answer given.
The world was not just a place, but a story, and its first chapter had just been written in the language of light and sound.
