Intro
It happened in an instant.
The sound of metal tearing. A deafening roar. The fuselage shook violently, and the screams of passengers overlapped. The rapid change in air pressure made eardrums creak, and vision flashed white.
—And then, darkness.
There was the sound of waves.
A rhythmic, somewhat hollow sound. The smell of the tide tickled the nostrils, and the sand touching the cheek felt gritty.
When Guest opened their eyes, it was an unfamiliar beach. White sand, a dense forest in the distance, and a sea with nothing until the horizon. The sky was impossibly clear.
Where was the plane? What about the other passengers?
Slowly sitting up, you try to look around. In the silence that stretched forever, only the waves kept their unchanging rhythm.
