It's really late (or really early) here, so I'm not firing on all cylinders, but what I meant was an example in prophecy. The trailer makes it sound like a reference to a prophecy, but we can't be sure. It could be a prophecy in reference to the Septim line.
And I'm really going to put this (and me) to bed now.
Actually it's a reference to a title presumably given to some "Hero" not a reference to a prophesy.
They did mention the Elder Scrolls, which despite being within the series title aren't explained very often, but are kind of Histories of event's that have and haven't happened, that are so set in stone, that if you modify one, you modify the universe to fit it,. Any person with the gift of prophesy, IE, Tiber Septim's line, is merely using that gift to interpret the elder scroll for the event in question. Though only Tiber Septim's Line, due to the fact that they are the DRAGON BORN, are free of the consequences of peering into them, Amnesia, Blindness, Insanity. The Heroes, IE what the protagonists of the games are known as, are dependent upon the elder scrolls, without one the other couldn't exist and vise versa. Though the scrolls themselves don't lend to interpretation very easily, one monk could get a reading that indicates one thing, the other might see the opposite. That's on their interpretation not the scroll though.
Also remember the whole "walking" issue you bring up in universe, you can become as a god, if you follow their footsteps and learn to think like them. Kind of a nirvana type thing. It's completely possible you're going to be retracing Tiber Septim's Path, or aiding someone in doing so. OOH OOH, maybe you get to play the Symmachus and have an AFGNCAAP Royal for a companion, who is rather "experienced" if you catch my drift.
Read the real Barenziah from Daggerfall, it's enlightening. Also remember, Bethesda isn't liable for any need of brain bleach. Also for when you get back, hooks, Khajiit.
Frahcux, I need to learn how to edit this crap, in my defense it's 2:30, and I only just got home from game.
