I've had this story idea floating about my head for awhile and I wonder. Considering the Seal that bind Shilen? Would it be possible do you guys think, that a living person could be the last Seal? that it continued won through the family, and as long as a single member of the family was alive, the seal would stay intact? Just curious.
Stand right next to the Seal and look at your mini-map at the top right of your screen. You will see that the land DOES exist beyond the Seal, so there at least is something beyond that wall......
