In this world, a God known as Dea has warned the world's population of the impending rapture very early in earth's history. It has been well known from the begining of recorded history that the rapture would occur 100, 000 years from now on an exact date. During that time period, certain signs and events occur with no doubt that they come from God to slowly lead up to the final days as a reminder, and have been well documented. Now, we are within the last 1000 years of this world's cycle, in which humans both living and dead will be absorbed by God and the world will be set. The final generations of this period will live to witness the last millenia of this cycle.
Humans have an average lifespan of about 200 years. Most people go through life wanting to leave some kind of impact, in order for them to be remembered. Some want to leave an important legacy of achievement, so their names and accomplishments won't be forgotten. Others want to make a better future for their children so that they can enjoy a better life than they did. Whatever the reason, it serves as a motivator for us to leave something behind to say that we were here.
However, knowing exactly when the world will end and the moment of your death changes things. The final generation understand that their legacy will be non-existent after the world resets. The next version of humanity will have no knowledge of them, making whatever their achievements were pointless. Their memory and history of their world will become irrelevant, as if they never existed.This will become more pronounced the closer you get to the final date. Everyday will be a party, filled with orgies, drugs, and drunken debauchery to celebrate the end of the world. (We are all going to die anyway, why not go out with a bang? It is better to burn out than fade away afterall). Or fatalistic, anti-social behavior that leads to chaos and anarchy.
Now we have reached the final generation of the planet, who will live to see the last days of the world before the reset.The goal is to keep society running as smoothly as possible, without any disruptions, either by nihilistic attitudes or lecherous activities. People should go on as normal as possible until the apocalypse, where they would be consumed and absorbed by God to become one with the human consciousness.
How can I accomplish this with the final generation?
