After the catastrophes caused by deforestation on Earth, the world is no longer the same. Deforestation has caused the extinction of almost all species.
The trees that survived began to produce pollen that contaminated anyone who breathed it, causing terrible mutations. The humans who survived were sent to bases commanded by a greater ruler, called "Rocom".
