【異世界ファンタジー】古代の司書が守る海底図書館のケルトBGM｜作業・読書・睡眠・リラックス

異世界の旋律 Fantasy Music Long ago, there was a kingdom above the sea. Magic lanterns glowed in its tall towers, bells rang through its white stone streets every morning, and in the royal library, spellbooks gathered from across the world quietly slept. But one night, the kingdom sank silently into the sea. The voices of its people, the lights of the city, and the wind that crossed the open squares all vanished into the blue depths below. And yet, the library was not lost. Protected by an ancient magical barrier, not a single drop of seawater enters that place even now. Tall bookshelves, stone pillars, and countless old volumes continue to breathe quietly within the long flow of time. Outside the windows lies a deep blue sea. Glowing fish drift slowly past, and in the distance, the shadow of a great whale glides between the towers of the sunken kingdom. Inside the library that no one visits anymore, there was one librarian who continued to protect the books alone. She was an ancient mechanical doll, created long ago by the kingdom’s magical engineers. She looked like a person, read books like a person, and gently lowered her eyelids like a person. But around her temples and along her neck, traces of ancient mechanisms remained, delicate as fine golden filigree. How many years have passed since she lost her masters? Even today, she softly places her hand upon an old book on the desk. A pale blue-white light spills from the pages, illuminating her fingertips and reflecting distant memories deep within her quiet eyes. “...It is still here.” The words are not spoken to anyone. They are not meant for someone she is waiting for. They are simply a way to confirm that the knowledge of the lost kingdom still remains in this place. This music is a gentle Fantasy Celtic background music piece that stays close to the silence of that underwater library. For reading, work, and the quiet moments before sleep. I hope you can gently listen to the story that the ancient librarian has continued to protect at the bottom of the deep sea. This is a place to softly listen to the continuation of a forgotten tale. ━━━━━━━━━━━━━━━ On this channel, we share relaxing Fantasy Celtic / Fantasy Music / background music inspired by medieval fantasy worlds.
