Year: 3016
Earth is now a ruined expanse of desert, the destruction of its ecosystems and environment absolute.
Fortunately for mankind, they developed the technology to survive in large biospheres, with barely a hundred of them scattered across the globe.
As more and more survivors trickle into the biospheres, the struggles to build more continues.
However, there are those who choose to live in the desert, gathering what water left on the planet with advanced technology, some who live as pillaging bandits, and still more taking up the most dangerous job of all: transporting good between the spheres. Kim Taehyung is one of them. Not just one of them. The one who leads the way across the deserts.

Pathfinder.

In a biosphere on the ruined Earth's surface, a young girl lives a poor, happy life. Her parents are merchants, spending much of their time earning their keep for their only child to study. They need to spend frugally, but their lives are good, in their own eyes.
Thing is, biospheres are just giant bubbles of precisely controlled plates of metal. When a mistake is made...
When the world around Hayoung collapses into dust, she finds the most unexpected of rescues, and is plunged into an adventure she never thought she'd get into.

Marooned.
