Andrew Ryan Sr. sought to avoid scrutiny from the government and the oversight of world. To escape from the world, he attempted to construct, in secret, an underwater city. He would call it Rapture. His dream, however, crumbled around him as the very thing he was trying to avoid kept him from disappearing. He was constantly watched by the government, keeping him from slipping away. He knew dream of Rapture, his paradise beneath the sea, was something that he would never see in his lifetime.
He would not allow the dream would die. Andrew Ryan ensured that there would be someone to continue on in his footsteps, working until his glorious vision had come true. Thus he created his ace in the hole towards making so that eventually his dream would become a reality. Andrew Ryan Jr. was 'created' with that thought in mind as he merely had a son to ensure that his dream would continue. Since he was able to avoid oversight he was able to indoctrinate his son, the boy was the perfect replacement for him. Alas, when Andrew Ryan Jr. attempted to continue the work of his father, he too failed in managing to get away from the governments but managed to avoid oversight like his father.
When the son had failed in the mission given to him by his father, he in turn had his own son. He indoctrinated his son Andrew Ryan III as he was, all for the sake of bringing his grandfather's vision to life. The Ryan Family's company, Rapture Industries, had grown far beyond what had been at the height of the reign of his grandfather. It dwarfed the Rapture Industries of the past by leaps and bounds, allowing the grandson to overcome the scrutiny that stood in the way both his father and grandfather.
Though Ryan III was having problems selling people on the idea of Rapture itself. They were not as open to things as they might have been during his grandfather's day. Though he had everything he needed for himself, the Grandson of Andrew Ryan Sr. did not have the man power or the other industries to invest into the dream of his family. This was until he was approached by someone claiming they were from a country where there were many people interested in what he wanted to do.
Having nothing really to lose Ryan traveled with them to this place. Which was located in place that could not be seen on any known map of the world. In this country he had what he needed to finally start the building of Rapture finally after all of these years.
The spot that his grandfather had originally picked was a place he thought was not a good place anymore as they would not be avoid detection anymore. Sure it was in his grandfather's day but that was no longer the case anymore. So he decided to relocate to place hundred of miles off the coast of where this country was that was hidden from the all kind of maps was.
Told that it was hidden from the rest of the world because of massive events that happened in the past. They did not have proof of what was legend and what was fact. Though the idea of ancient being with ten tails being split into nine beasts was commonly accepted. When Ryan claimed that was not possible he was shown pictures of the beasts as they brought havoc and chaos to the people on the continent. These people were mostly oblivious to country that interested in Rapture, each having there own problems to worry about. This country was left alone as they never interfered with the mainland and its affairs.
After everything was settled, the construction of Rapture began as the city was even today still a massive undertaking as they were building under the sea. As for how Ryan was able to get supply from his company to the Rapture construction sight without anyone noticing or carrying. He used a vessel that was constructed from the ore of the hidden continent, allowing it to hide from modern technology.
During the building process there where sea slugs discovered that would prove most useful in Rapture once it was finally completed as people flock to the suppose utopia under the sea. A modern age Atlantis fully of wonder and sight that were unique by anyone's standards be it from the world at large or the hidden segment of the world.
