Tale of Three Gates

In a world where portals just start out, others already have a good run, but one family makes a thing out of it to build character and get them ready for the real world, by sending them off to another. It all starts with one being thrown into another world and told to make it through three, and learn the ways of life not knowing anything about the one ahead of him, even if it is out to hunt him. Knowing nothing about the world he is to be thrown in, one has to make the best of what they have the knowledge of to make it their own and see it through. Is it true that if you throw someone to the wolves, do they really come back leading the pack?
