When a disaster called "Silence" swallowed up global water resources, the world became an endless sea of sand. The surviving human beings huddle under the towering "dew tower". Classes are ruthlessly solidified by the distribution of a drop of water. The nobles at the top of the tower are extravagant, and the poor at the bottom of the tower are thirsty.
Leia Dust, a girl from the bottom of society, was born with the forbidden talent of listening to quicksand, and could identify the buried echoes of civilization and the lamentation of history from the wind and sand. In order to find her brother who disappeared after being drafted into the Death Sand Sea to find the legendary oasis, she resolutely stepped out of the high wall and broke into this dangerous wasteland.
The sharp claws of strange beasts in the sand, the pursuit of powerful people on the top of the tower, the shocking conspiracy that has been concealed by the yellow sand for hundreds of years... Leia's power is awakened in life and death tests one after another. When the quicksand begins to tell her the truth that "silence" is not a natural disaster, she will use this unique echo to stir up the foundation of rule and play a hymn of resistance and hope for this silent world!
