Ours is like the story of a man slave who is convinced by his master that he has been set free but is kept on a very long leash that only the master is aware of. And so the master determines how far he can get with the leash on and then goes ahead to set up a hut with a bed, warm food and water, and the just 'freed' slave after days of walking and exhaustion comes across this prepared place of comfort with nobody in, no one in sight. Grateful for answers to his prayers, he lives there for a few days, gets as much rest as he can so he can continue his journey; and then just as he's about to leave, another 'freed' slave shows up this time, a female.
She's also pretty exhausted and of course he feels obliged to help having been in her shoes not too long ago, she's nursed back to health and somewhere along the line they fall in love and have a child. Then there's no reason to leave anymore. Hence, both these slaves are still convinced that they're free, dancing to the master's tune and never get to the point where they find out that they're on a leash, they weren't ever free.
Some years later, this child grows up and ventures out of that area only to realise that there's a whole new world unknown to his parents. He rushes home excited about the possibilities that await them, eager to convince his parents about what he has seen. After much back and forth talks, the parents agree to explore this new world with him. But the master can't have that, he can't have them finding out they weren't ever free.
So few days before they set out, this young man is out on one of his expeditions and returns home 'mysteriously' ill. After a few days, he dies. His parents are then convinced that leaving was a bad idea they shouldn't have considered it in the first place. They then spend the rest of their years passing on that culture and myth about a world outside that kills anyone who steps in it. Ending up exactly where the master wanted them in the first place, never realizing that weren't ever free...
