Church of the Walls

The Wall Cult is a religious organization that considers the Walls to be sacred, with a lot of religious and political power within them. Some of the cult's members possess knowledge about the Walls that is hidden from the public.

Belief
The cult worships the Walls over everything else, believing them to be sacred and untouchable. They worship Wall Rose, Sina and Maria, and think it their responsibility to protect the Walls from any "impurities" like humans, rails, or cannons. They have been shown to be unknowingly loyal, to the point where they would sacrifice their own lives if it meant the protection of the cult's secrets.

Members
Among the members of the cult are a variety of different people from different places. There are also priests who represent the Wall Cult. An unknown number of priests are involved in deep secrets regarding the Walls, which also includes information regarding the Wall Titans and possibly even the mystery of the Titans. The only notable member of the cult is Pastor Nick, who is eventually murdered by the cult after seemingly revealing some of its secrets.

Affiliation
The Wall Cult is directly involved with the government, as seen when one of the priests attended a meeting with the fake King. Traitors are treated without any mercy. When Pastor Nick decided to help the Survey Corps, the central branch of the Military Police Brigade was sent after him, which caused him to be tortured and murdered.
