Welcome to Potentia(no not the city in Italy), the city of powers. Here there are many people who have or have gained powers. The empowered people are sorted into one of two groups Hero or Villain, but occasionally some don't really chose a 'side'. After many years the group of superheroes called the Omnipotent (they aren't actually omnipotent) defeated most of the super villains in Potentia, leaving only the most trivial and weak of the villains free. From then on Potentia was a peaceful city. Well that's how it seemed.
-------------The truth is there is corruption in the heroes of Potentia. Most of their greatest achievements where set up and faked. Only a few of them even actually have a power or special skill. Regardless of whether you were one of the few people to know about the fake heroes or if you were just a regular person you received a letter. It told you to come to the abandoned warehouse near the Omnipotent's base. It said they needed you help to uncover the evil within the heart of the city.
