Hometown

Little is known about the place where Bertolt, Reiner, and Annie originated. It is said to be located somewhere outside Wall Maria, and is alternately referred to as the "village" or "homeland" of Reiner Braun, Bertolt Hoover, Annie Leonhart, and Marcel. It is one of the greatest mysteries of the series, with little revealed about it. Flashbacks to Annie's childhood show the clothing styles and housing are similar to that of the people living within Wall Maria. The only certainty is that there are in fact humans surviving outside of the walls, whether they are also Titan Shifters or not is unknown.

The people from this land refer to themselves as being "warriors", a distinction also made when Ymir refers to them. While it is unknown whether all those living there are Titan Shifters, all three surviving characters from that location possess this ability. Ymir states that they possess the "Power of Titans", and she obtained her powers by stealing from them. As a result, she is a fugitive and greatly fears being killed by them should they catch her. She believes that Historia Reiss may be valuable enough to them to earn a pardon, and would not be harmed if surrendered to them.

In 845, they launched an attack against humanity and sent at least three agents into the Walls in search of the Beast Titan and something they refer to as the "Coordinate". However, Ymir believes that they possess influence even within humanity's lands, claiming that no one is safe from them regardless of where they might hide. Their agents are similarly desperate to complete their mission, going to suicidal extremes in their quest to obtain Eren Yeager even though they have expressed doubts that he is indeed the Coordinate.

When Eren manifests the power of the Coordinate, he gains the ability to command a horde of mindless Titans. Erwin Smith suggests it also has the potential to control normal humans, and had some role in not only the creation of the Walls, but also the memory loss suffered by humanity when they settled within them. While its exact nature remains a mystery, the Coordinate sought by the Titan Shifters is spoken of as a possession, and mentioned to have been taken from them.
