In 2023, the appearance of non-humans sky rocketed. To "solve" this, the dominating species, humans, chose to separate every species by a wall. The walls took over half a century to build, even with modern technology. At that point everyone was forced to go into their respective places, triggering mass havoc as they tried to escape or kill those who took them in.
Three hundred years later, the walls are being torn down. Things are not like they used to be, when the creatures lived in hiding. It's hell. It wasn't the greatest idea to take down the walls, as after they were released, a quiet war started as all species tried to kill each other off without being caught, as century-old hatred has returned. Maybe they shouldn't have put them up in the first place.
Welcome to the war.
