Walls



The Walls were built more than a century ago, when humanity started to become extinct at the hand of the Titans. In response to this looming threat, the humans made huge walls to protect their last stronghold. The walls reach about 50 metres in height and reach four or five times a human's height below the ground. They also seem to extend surrounding the human territory underground and were once mistaken for bedrock. The tops of the walls are lined with cannons, which can fire on approaching Titans.

The walls are too long to be guarded in their entirety. To account for this, each one has four towns on their periphery. As Titans are drawn towards large concentrations of people, humanity can focus its defenses at these towns.

The interior of the walls seems to contain numerous dormant Titans. While no details have been given, it has been suggested that the walls were originally created by Titans using their hardening ability.

Two of the few people who know about the Titans in the walls are Pastor Nick and Historia Reiss. Pastor Nick is a foremost member of a cult which considers the walls to be holy. Historia was a formerly high-born lady and presumably knows about the walls because of that.
