The pulse of reality

People with abilities are generally treated with caution, because they are physically stronger, even though there are few of them.
Ordinary people welcome heroes and oppose villains; society believes in good and evil and clearly divides villains and heroes, sometimes without even delving into the story behind the abandoned villain or the deceiver of the hero.
In the upper classes, they are trying to oppress them, and some even advocate for blood purity, although without mutation, people are not as physically strong.
Those with abilities themselves are divided into heroes and villains. Heroes save the city from those who decide their new abilities are a way to claim the world. Heroes and villains don't necessarily wear costumes, but they mostly do so to keep their identities secret and avoid questions from their superiors.

In 3104, scientists were trying to create something unique and experimented with food, genetics, food additives, and other things that could affect people's immunity.
The experiments were unsuccessful and, on the contrary, only made matters worse. People's immune systems began to weaken, making them vulnerable to the outside world. About 50 years had passed since the experiments, and humanity was on the brink when a new mutation began to form and people with abilities began to emerge.
Over the next 10 years, the mutation developed and scientists studied it; people with it were less vulnerable to the world. Children born with the mutation were rare and were marked from childhood with a small symbol on their shoulder in the shape of the letter A.
The variety of abilities was great: telekinesis, cryokinesis, pyrokinesis, hydrokinesis, geokinesis, aerokinesis, cryokinesis, chlorokinesis, zookinesis.
There are also forbidden abilities: telepathy, necromancy, biokinesis, and chronokinesis. The chances of having a child with these abilities are small, but not zero.
