From the introduction: This story takes place in a world struggling with the aftermath of an environmental disaster. In Reborn City, Pokémon are scarce, the lake has more poison than water, plant life consumes whole wards quickly and without warning, and the population rarely ventures outside of the city. What's more, the local terrorists already have the region in their clutches. Are you a new trainer hoping to take on the Reborn league, or something else entirely? You might find yourself caught up in much, much more.
