One century before the events of the main storyline the 145th Eldian King, Karl Fritz, found himself disillusioned by the powers his ancestors had granted him and guilt-ridden over the destructive path the Eldian monarchy had taken. He orchestrated his nation’s downfall, allowing the nation of Marley to rise up in rebellion. In the process, Eight of the Nine Titan powers were stolen by Marley. Fritz took a handful of his people across the sea to the island of Paradis to begin a new, peaceful nation. He used millions of Colossal Titans to construct three curtain walls walls named for Ymir Fritz’s three daughters: the outermost being Wall Maria (ウォール・マリア, Wōru Maria); the middle Wall Rose (ウォール・ローゼ, Wōru Rōze, sometimes pronounced like rosé) and the innermost Wall Sheena (ウォール・シーナ, Wōru Shīna, alt. "Wall Sina") which housed the Royal family and was populated by the wealthy and elite. Once the walls were complete, Fritz gave the outside world an ultimatum: should war be declared on Paradis, he would release the titans within the walls to flatten the earth. This, however, was a bluff since Fritz revealed to his family that he had renounced all war. If Marley eventually became powerful enough to overthrow Paradis, then he would accept that. He used his Founding Titan powers to create a blood pact which would instill this ideology in any royal family member who inherited his titan, even if they disagreed with it before. Meanwhile, Eldians that remained as second class citizens within Marley were treated poorly, and any form of dissent or disobedience was punishable by exile to Paradis: people were injected with raw titan spinal fluid, turning them into mindless, man-eating ‘Pure’ Titans which would eventually find their way to King Fritz’s walls.
