as long as I remember there have been the Walls not your ordinary walls I'm talking 50 meter high 50 feel thick solded concrete. no one knows who built the salls because everyone who did has died. But the walls aren't there for no reason, no there, there because of we were to leave the safety of our walls we would be killed by giant human like things we call TITANS. For as long as the walls have been here so have the titans and in said walls are 3 rings walls rose, sena , and maria and in smaller districts are city's I live in a district in wall sena called sheganshina evr since I was a child iv also known why the walls are there and why we are hiding from the titans. For you see I am the youngest granddaughter of the founder of our walled city.
