I know that somewhere in the before the fall manga it is mentioned that titans come mostly from the south. Have the survey corps ever traveled to the north side of the walls? I also read somewhere in the manga before the fall, that a city called naraka in located on the north side of the wall and its where some exiles live!

Can this city called Naraka be the home town of reiner, annie and bert?
