Religion

There was once an established religion in Homestead, but it had begun diminishing in popularity many years ago. Therefore, smaller cults became more popular as a way for people to express common beliefs about the afterlife. There is a small sect that knows the truth (or at least part of it) and maintains the advanced tech. They are simply following orders that have transformed into dogma. However, they do not know that they are in a dome and they do not know that the overlords they worship and think will save them have left thousands of years ago.
