The Gateway

In the book, the gateway is an old, twentieth-century metal structure, forgotten and hidden in the Parque das Dunas.

Origin
The book tells that the park gateway was a failed teleportation project created by american scientists in 1961 (55 years old). North American scientists have created the machine to explore the power of teleportation, exporting objects and people to other places and even alternative dimensions. At that time, the world was in the period of the Cold war and the United States was disputing innovative technological powers with the Solvietic Union, and for this, the teleportation machine was created. The Americans searched for an isolated and secret place to do these experiments, and nothing better than inside a rainforest in a Brazilian city that was air base, Christmas, and in the current Park of Dunes. However, for some reason, the project failed at that time and the machine stayed in the middle of the woods, abandoned and forgotten for years, until rediscovered in 2016 by the students of Max College.

The Discovery
In school trip in Dunes Park, a group of students players of Pokemon GO, sought pokemons in the park and were willing to disobey the orders of not adrentarem in the woods. They found the entrance to a trail, which perhaps, not even those responsible for the park decided to enter. But the adventurous students were fearless, and in an act of stubbornness, they entered the trail. They open the wooden block and enter the place, the girl in the group warns them not to enter, but it is useless, and a boy alleged that there was no problem, because besides there was no sign indicating prohibition, there was no one watching. The group continues exploring the trail and to their surprise, at the end of it, they encounter the abandoned metallic structure and covered with weeds. One of the students left the trail and went discreetly to tell others the discovery, and they were spreading to others, taking advantage of the distraction of the teachers. Until everyone stops doing what they were doing to go look. Student Amanda collected her school supplies when one of the teachers decided to ask where the students were going, and she invents that a monkey fell from a tree and was injured. Even believing the lie, the teachers mistrusted the students' movement.
