Prior to the grouping protocol, many of the city's residents lived with their families, with their friends, with their loved ones. Until twenty-three years ago. The government finally decided that people with different abilities were no longer allowed to interact past a certain age because of infighting and civil wars. The city was divided into eight sectors- Flight, Animal Communication, Hyper Intelligence, Super Speed, Precognition, Invisibility, Psionics, and Illusions- and the government enforced the segregation with the punishment of having your powers removed all together, and being placed outside the city walls.
Children are allowed to stay with their families until they turn 18. They are not allowed to use their powers if they differ from their parents until they are sent to their power sector. The children who differ from their birth sector's powers are usually bullied, outcast, or completely ignored by their classmates and instructors. The government doesn't do anything about this.
At the end of every year, the 18 year olds are moved from their birthplace to their new homes. They are normally small, barely decorated dorms in the schools. At the age of 21, graduate students are set freely into their new sectors to find work and make a living or a name for themselves. This is how the program works. And it's kept peace. But it can't- it won't- last forever.
