On Katrigern, the science of precognition was developed first by machines. Computers were designed to figure out what was the most likely outcome of events. However, human free will, seemed to be irreducible to material effects.
Still, they managed to terraform their home planet of Katrigern, and its primary moon of Lacia, and the secondary moon of Teklaz, and the nearest outer planet of Visgo. They had wars, but they soon found that with the aid of the Prognostication, that they did not need to fight. Things tended to turn out as the computers suggested they would.
However, the computers also suggested that the species would now enter a long, silver age of genteel decline. By rigorous logic, it could be proven that human was more than matter, but due to advocates for materialism, and due to the laziness of the mind...almost certain knowledge of the future was read as Absolute Knowledge and "Free Will is Dead!" shouted the intellectuals from every college establishment.
Well, with that rot growing at the base of the tree of civilization, a long genteel decline was the best one could hope for. The Materialist leaders knew better than what they preached in the classes, but power spoke louder than principle in their ears.
And then something happened that was not predicted. Certain people arose who saw clearly and logically, and worse, they had an imagination. They wondered if the human mind could be trained to do what computers do. And so with help from the well-wishing AI's that ran the Prognostication Service, they duplicated the effect, or so it seemed.
It looked slower, and less accurate. And the researchers let that impression stand. For they knew that it was, in its very limited, but specific way, more accurate. For a computer could take in all the facts, but a human could only take in a few. The only answer was that the human had detached himself from the body and the timestream, and stepped into the near edges of eternity to look at pages not yet turned in the Book of Time.
Eventually, there arose a great dissatisfaction with the intellectual elite, the leaders of society, and these researchers into Genuine Human Precognition were ready to step into the gap as the leaders of the revolutionaries. The combat between the Materialists armed with the weapons of war and of persuasion, and the Futurists armed with the common man, and precognition was the first, and last bloody war for five hundred years on either side. Unlike later accounts, the Futurists fully used the Prognostication Service as did their enemies. Romantic tales make it a matter of man vs. machine, but it was not. It was those who believed in the spirit and matter vs. those who only believed in matter.
The Materialists would not yield power even though they were vastly outnumbered at the vote. Instead, they manipulated votes which is as the precogs and the machines predicted. The machines predicted that the Materialists must win. There was no avenue for Precog victory. The Precogs looked into the future, and found a route so strange, so bizarre that no man would have thought of it, and they won.
Part of it was they saw the weaknesses of the enemy commanders. Many of these weaknesses of character had been unknown even to the person himself, or at least hidden from the machines to whatever degree they could. But the precog could see it, and plan on it.
Now hundreds of years later, everyone can see the future. But there are so many futures that could be. The problem is, which of the many futures do people want to live in.
One can see a future where Joe marries Mabel, and one where Joe marries Susan...and futures where either is happy, and either is unhappy. And futures where Joe becomes a monk. And Joe, Mabel, and Susan, and Joe's competitors for Mabel and Susan's hands can see this too.
So Mark might point out to Joe that he would be a much better person as a calligrapher and monk, and to Susan that she could buy calligraphy from Joe thus making her happy to see her friend, but that she was not in love with Joe yet, instead she could choose the future where she would fall in love with Mark. And Mark could offer Mabel support in her vision of the future where she marries Rick against the wishes of Stephanie who also wants to marry Rick.
Most of what people do is try to work out coalitions to create the future they want. However, its been found that the best way to get something close to the future you want is to help out everyone. No one will likely get everything they want, but help out everyone as much as possible,and that creates a brighter future for all.
And so they vote on the futures to create daily.
And the verser may arrive in the run-up to the Materialist War, or he may arrive in the Utopia. The Utopia also can be the contingency world for the Materialist War setting.
In Utopia, the verser is immediately going to be recognized as a stranger. No one's seen him in any future. Pretty quickly people are going to go from 'you're not from this town, are you?' to 'you're not from this planet, are you?' And then when people do look into the future, they will see him mentioning who he is.
This won't necessarily be a bad thing as these people are very nice. However, they will generally know what he's going to do before he does it.
And if he's an evil verser, he may get the surprise of his life as they will know what he is, and what his nature is before he's revealed it by his actions.
I would say that living in Utopia would be quite weird.
