Walls

The **Walls** (壁 *Kabe*?) are three, large circular structures that guard the remnants of humanity and contain the rest of their land. They were built sometime before the Year 743 by a large group of people in order to protect the rest of their land and their lives from the threat of the Titans. This largely succeeded, due to the height and strength of the Walls, until the walls were finally breached over a century later by the Colossal Titan and Armored Titan.

## Description

The Walls themselves are exactly 50 meters in height from top to bottom and lined with cannons at major human population areas, typically the twelve districts. They are presumably made from an extremely durable substance, although one that can be destroyed with enough force - as demonstrated whenever the Colossal Titan kicked open the gate of Shiganshina District.

The districts themselves equal to twelve, with four districts on each of the three Walls at the four cardinal directions - north, east, south, and west. They extend outward from the typical length of the Walls themselves. As mentioned before, these districts are usually the places that are guarded by cannons mounted on the top of the Wall, as well as a large collection of Garrison Regiment soldiers. The cannons themselves do not extend to cover the entire circumference of the wall, due to the fact that the Walls are simply too long to cover.

The distance between the Walls is considerable. Between Wall Maria and Wall Rose is a distance of about 100km, between Wall Rose and Wall Sina about 130km, and roughly 250km from one side of Wall Sina to the other side. Factoring math into the equation, this means that the perimeter of the Walls themselves is slightly over 3,000km, and the area inside the Walls over 700,000 km².

## History

A large portion of the history of the Walls remains shrouded in mystery, such as the method used for their construction. However, it is common knowledge that the Walls were erected rather quickly over 100 years ago whenever the Titans suddenly appeared one day. It can be assumed that the twelve districts were also built around this same time. They have stood ever present and tall since their construction, only showing small cracks and signs of weathering over time.

## Story

### Fall of Shiganshina arc

In the Year 845, Wall Maria suddenly comes under attack as its southern district, Shiganshina, is breached by the massive Colossal Titan. Multiple Titans begin to filter into the district via the hole in the Wall, which leads to a massive loss of life and a general evacuation of the city. As the district is beginning to seal off, an Armored Titan suddenly appears and destroys the outer gate, effectively rendering the entirety of Wall Maria useless.

Despite not being attacked directly, the other three districts of Wall Maria are evacuated as the refugees all flock to Wall Rose. This crisis is known as the Fall of Wall Maria, effectively eliminating 25% of humanity's remaining land and becoming the first breach of the Walls since their construction.

### Humanity's Comeback arc

The situation inside Wall Rose and even Wall Sina becomes hectic, as food supply begins to dwindle rapidly due to the sudden influx of refugees. Two months after the fall, the Royal Government organizes an expedition to attempt to regain some of the lost food still within Wall Maria's borders.
