Hometown

The Hometown, also referred to as the homeland or the village, is a mysterious land located outside of Wall Maria. The three main antagonistic Titan Shifters originate from there. In the year 845, for reasons unknown, the Hometown sent out four Shifters with a mission. Little of it is revealed, but it involved destroying the Walls and locating a power known as the Coordinate. Alternatively, they are referred to as warriors.

History
So far little is known about the land Annie, Reiner, Marcel, and Bertolt hail from. Its location, size, and population is also unknown. In Annie's flashbacks, the clothing and housing is similar to the people living in Wall Maria, although in a, somewhat, forest-like setting. The Hometown appears to hold a considerable influence in the Walls. Ymir, a criminal to them for eating Marcel, fears that wherever she goes, they will find her. She believes that the only way to earn a pardon would be to hand over Historia Reiss, the illegitimate child of Rod Reiss. Because the Reiss family is the true rulers of the Walls and holds knowledge about the Titans, Ymir believes that Historia wouldn't be harmed if handed over. Indeed, Reiner says that his goals somewhat align with Ymir's because they both want to protect her. Despite this, the Hometown appears to have malicious intention towards the Walls. As part of Reiner and Bertolt's mission, they were to destroy the Walls, thereby exterminating the humans inside. They were also sent after the Coordinate, a mysterious power tied to the Reiss family, and locating the Beast Titan. So far, they have succeeded in destroying Wall Maria, decimating a third of humanity. Whether or not everybody in the Hometown is a Titan Shifter is unknown, although all four of the agents are.

Agents
The Hometown has sent out four agents to the Walls for an unknown mission. The mission appears to be exterminating humanity, although Reiner states this has changed. On the way to the Walls, Reiner, Marcel, and Bertolt encountered a Titan outside of Wall Maria. The Titan reached out for Reiner, but Marcel pushed him to safety, sacrificing himself. This Titan, Ymir, ended up absorbing his powers. Mr. Leonhart, Annie's father, appears to be part of this mission, relentlessly training her to do it, although he later apologized for it and said that if she felt it necessary, she could abandon her mission; however, she didn't consider this an option.

Once they made it to Wall Maria, Bertolt transformed into the infamous Colossus Titan and made the first breach in 100 years of peace, allowing Titans to enter the city and consume the inhabitants. Reiner, as the Armored Titan, broke the inner gate, killing several soldiers and allowing the Titans to enter Wall Maria. It has been theorized by Armin Arlert that Annie, in her Female Titan form, may have participated in the attack, possibly by using her Titan summoning power to lead the Titans to Shiganshina after Bertolt breached it or even after, leading Titans to the human towns, however this has yet to be proven. After this, the three assumed human identities and lived in a refugee camp until they were old enough to enlist in the Military. They joined the military, saying that they came from a mountain village in Wall Maria to avoid detection.

The Hometown appears to have been waiting years for this mission. Annie has apparently been trained since birth to complete it, as she remembers spending every day, from sunrise to sunset training and learning techniques. Annie has been shown to be very dedicated, even going to suicidal extremes, to the point of killing her former comrades and innocent people, shedding tears when she failed to capture Eren Yeager, and encased herself in an indestructible crystal in order to avoid interrogation. Bertolt and Reiner are both equally dedicated, both of them attempting to kill their comrades and members of the Survey Corps after their identities were revealed. However, they both carry mental scars and heavy guilt as a result. Bertolt talks of not having a choice in the matter and said that he was very sorry for being the Colossus Titan. Reiner has experienced fugue states due to being unable to cope with guilt, suppressing his true memories. In these fits, he believes himself to be a human soldier, although Bertolt is able to help him out of these states by reminding him that they are warriors. While Annie doesn't appear to hold as much guilt, she apologized to a corpse a month before going on her rampage as the Female Titan. The three know many secrets of the Titans, such as that they were once people and are quite skilled in using their Titan forms compared to Eren. In their Titan forms, they all share a lack of skin and abilities unique to them, with Bertolt's being his steam generation, Reiner's being his hardened plates, and Annie's multiple abilities, including selective skin hardening and Titan summoning.

The Beast Titan appears to be an individual of great significance to the Hometown. When Bertolt and Reiner encountered him at Utgard Castle, Ymir described them as excited, gawking children. The Beast Titan is a Titan Shifter, with the ability to converse in Titan form, command nearby Titans, and possibly create them. Reiner faced him in Titan form and the Beast Titan easily won. He has since persuaded the two into helping him obtain the Coordinate, and appears to hold a considerable influence over them, as he said that Annie's rescue could wait, with the two holding the belief Annie had been tortured for months.

Another part of the mission includes locating and stealing the Coordinate, currently in the possession of Eren Yeager. They speak of it as a possession and having been stolen from them. Bertolt and Reiner highly doubted that Eren was indeed the Coordinate and were heavily shocked when he commanded nearby Titans to eat the Smiling Titan and then to attack him. The Reiss family owned the Coordinate previously, using it to build the Walls and modify the memories of humanity, until it was stolen by Grisha Yeager. The Beast Titan says that stealing the Coordinate is more important than rescuing Annie. Annie states that she doesn't know what will happen to her after she completes her mission, although she thinks she might just receive a merit if she succeeds. Annie said that if she managed to capture Eren, her mission would be finished and she could return home.
