All About Wall Maria in Attack on Titan
Wall Maria was the outermost Wall of the human kingdom. Like the other Walls, Wall Maria was approximately 50 meters in height. In 845, it was breached by the Colossus Titan and Armored Titan and its territory is lost to the Titans. Six years later it was repopulated, after the hole in Shiganshina District was sealed by Eren Yeager and all the Titans inside the Walls were killed.
All About Carla Yeager in Attack on Titan
During her youth, Carla worked as a waitress in a small bar that Keith Shadis frequented. One day, Keith brought along Grisha Yeager, who had recently been found lost outside of the Walls. Carla reprimanded Shadis, thinking that he wanted to beguile Grisha into joining the Survey Corps, but both men denied this.
Sometime later, Carla became ill with a disease that plagued Shiganshina and was urgently taken by Shadis to Grisha, who had become a doctor. However, she was more worried about her parents, but Grisha ensured her that everyone would be fine. He eventually managed to save Carla and her family, and Carla hugged him as she rejoiced in tears.
They soon fell in love, and sometime later married and had a son named Eren. When Shadis returned from an unsuccessful mission as commander, he approached Carla with a young Eren and she expressed her and Grisha's worry for him. Out of spite, he accused her of being ordinary and lacking in imagination. However, Carla stated that some people do not have to be special or greater than everybody and existing on its own was special.
Carla is the first character in the series who is shown being eaten by a Titan.
