So, another question about Attack on Titan.
So in the Manga, and by extension, the Anime, it is revealed that certain people, Eldian IIRC, are transformed into Titans by injecting them with Titan Spinal Fluid. These people are then thrown off a large object, and transform into Pure Titans a short while later.
Now I got to thinking, Is this large object yet another wall placed on the Island of Paradis? Like the three walls protecting Humanity on the Island itself? Or is this just a staging area for the transformation of people in Pure Titans?
