Overview (Target: 160-220 words):
The narrative of this season is shaped by the revelations found within Grisha's journals, which fundamentally alter Eren's understanding of the world. Previously, the belief existed that a rugged and free land lay beyond the walls, but these memories reveal that a whole other world exists, one that is characterized by oppression and war. This discovery challenges the long-standing ambitions of the Survey Corps, which now appear small and naive in the face of this new reality. For generations, the Survey Corps has fought to uncover the secrets of the titans' origin and protect humanity, which has lived in fear behind enormous concentric walls. Centuries ago, mankind was slaughtered to near extinction by monstrous humanoid creatures known as titans, forcing the remaining population to shelter behind these towering structures. These man-eating giants are noted for consuming human flesh, seemingly out of pleasure rather than hunger. As the truth of the world beyond the walls comes to light, the characters must grapple with the reality that the struggle for survival is part of a much larger, more complex global conflict involving systemic oppression.
