Which to me points towards a theory of some kind of spiritual setup. Remember LOST? Yeah, maybe something like that. Maybe the whole "there you have a pseudo-medieval society and they´re fighting monsters"-appearance is all fake. Maybe we´ll suddenly tap into the scifi-genre. Who knows.
All I know is that, unless the author sucks and didn´t give a shit about logic, there is so much more to it than we currently know.
