Beyond the safe walls of humanity, there was thought to be no intelligent life. Seeing as the Titans did not show signs of responding when spoke to and, put plainly, just ate people. When the three solid walls stood high in the sky, people felt safe. The titans have never been able to get in, and how could they? The walls were far taller than any Titan.
Until that fateful day, when the gate was smash in much like how a toddler would kick over blocks they had stacked. That day, humanity received a grim reminder of the true fear they lived in, the fear of the Titans. The amount of people wiped out was shell shocking, and the loss of land was catastrophic. The effect it had on humanity would never fade.
Destroyed was the feeling of safety that the people felt. Smashed into rumble, much like their precious wall.
This was 7 years ago.
Now humanity has made a comeback, granted it is small, but it fuels their goals to regain the fallen wall. The fate of humanity rests on the shoulders of a 16-year-old boy who goes by the name, Eren Jaeger. He who can turn into a titan, an odd ability shared by a few others. Little does he know that there is so much more at stake. The plane of existence where we all resign is at risk because of the imbalance.
Like I'd let him screw up the universe.
This is where we come in. Not that we really wanted to be there, but the Gods get antsy when large burdens befall mortals.
