Un bosque

"Un bosque pasado el muro" is a story about how two people who come from very different places, Irlen and Zúah, meet and embark on an adventure together, following what the tales book tells them to do through the different biomes of the world.

There is a planet divided in two sides by a colossal ancient wall.
One side remained almost untouched, with virgin forests and thriving ecosystems. Many conscious species, some human like, live an archaic lifestyle in touch with nature.
The other side is more technologically advanced, living very similarly to our modern lifestyle, but with no space travel or travel by plane. Almost no one cares about the other side, and it is not teached at schools. Most people believe that there is nothing on the other side or it is just a wasteland.
The technological side is severely eroded and deforested, everything is covered in cities and concrete. All of their clean air comes from the other side, but most are ignorant to this.
