Season One

About the Walls Humanity lives surrounded by three walls. The outermost wall is Wall Maria, the second is Wall Rose, and the centermost wall is Wall Sina. The Walls are separated from one another in roughly equal intervals. There is a distance of about 100 kilometers between Maria and Rose, and there are about 130 kilometers between Rose and Sina. From Sina, it's about another 250 kilometers to the center of the interior.
A Rough Diagram of the Human Activity Zone This diagram (which referenced one in the original manga) provides a more intuitive idea of how large the area left to humanity is. What lies beyond Wall Maria is a mystery. The elevation increases as you approach the center of humanity's activity zone. This area is also rich in natural resources such as water, ore, and natural gas.
ODM Gear Training ODM gear training is a difficult process, meant to force the cadet to adapt from moving in a flat two-dimensional plane to a three-dimensional space. High endurance, strong legs, good spacial awareness, and nerves of steel are requisites.

Wall-Mounted Artillery Prior to the ODM Gear, cannons were humanity's primary anti-Titan weapon. In order to make up for their lack of mobility, the cannons were placed on the Walls, and defensive improvements were made to the Walls (for clarity) as well. Grapeshot: Low lethality but effective at stopping Titan movement. Shells: Deal a large amount of damage, but their extremely low accuracy makes it very difficult to aim and hit a target.
Ultrahard Steel A material that is both hard and flexible, allowing it to tear through Titan flesh. The "single-edged swords" that use the material are widely known as anti-Titan weapons. Refining Ultrahard Steel requires the use of blast furnaces that exist only in the Industrial City, meaning it can't be made anywhere else.
