The second, however, is tenuous. Heroes are real. Throughout history, the outcome of wars, nations, and entire populations of people have depended on the shoulders of one or a small group of men. But, there was no ancient scroll that prophesied Churchill and FDR beating Hitler. It just happened. So, while I admit that the player character will almost always have to be the hero (unless he ignores the main quest) I would prefer he not be "destined." Maybe that's contrary to the Elder Scrolls mythos, where even the future is written down. Certainly, the title "Dragon-Born" implies fate, as he was "born" to fill this role. It would please me greatly though, if there was no prophesy, and your character simply earned that name in one of the early main missions, where after being swallowed by a dragon, he/she cuts himself free, thus becoming "dragon born."
*Spoilers! Youve been Warned!!*
The stories tend to be quite varied. it seems only otherwise when people dont want to look. First off, yes: The hero "Of uncertain parents, born on certain time" described best from morrowind how it works. Your character provides the lynchpin for progress, for whatever reason. In Arena, you were a prisoner, the only one who could end the Similacrum. In Daggerfall it gets WEIRD. You actually have to give a totem to one faction, but all endings are cannon. This resulted in the "Dragon Break" one of at least two events of unparalled proportions. What were fourty-four states became only four in less than two days time. This was rather chaotic. This was because *all endings* happend truly, even contradictory ones: Mannimarco, Numidium, etc. Thats what you do in Daggerfall, choosing your faction.
The second dragon break occured with the formation of the Tribunal and Dagoth Ur. he was corrupting the world, but by not by his own hand. The remains of Lorkhan, called Akulakhan, was going to be revived as a second numidium. Fortunately, you were able to destroy the insane Dagoth Ur, before a daedra prince proper reclaimed his Oblivion realm. With the tribunal weakened, both Akulakhan and the corprus and blight from red mountain wouldve swept across the world, an invisible threat rendering them too weak to stop Akulakhan.
In Oblivion, You were not sent to kill anyone, to destroy anyone. Merely to restore order. The world rested on your shoulders, not the tip of your blade; It was not just cyrodiil that sprouted oblivion gates, they were happening *everywhere* presumably including Akavir and Atmora and all those fun spots. and through your actions a new age, The first New Age since the games started. Your character effectively ends one empire that is ancient and was solid, which leads to the inevitable civil war.
Skyrim exists either during or after this event. And we have no idea what the threat is in this game.. I can tell you this much: It aint the dragons. Thats too simple. Oh, there will be dragons. Like Saint M'aiq said: "Dragons? Oh, they're everywhere! You must fly very high to see most of them, though. The ones nearer the ground are very hard to see, being invisible." but the threat will come from elsewhere.
So, you see my problem? the games were vastly different in scope and what happend and what you had to do in order to progress it. I simply do not see how you can consider these stories anything alike, except all resulted in a change in power that was almost definetly the correction of the dragon breaks that changed time as it was known to mundus. Theres not really that much linking them together..It really seems like you're grasping at straws. We dont want another Oblivion/Morrowind clash. They are very different events, in every case, and follow a very different course.
I think you might just be..a tad biased. I think you have neglected the obvious: The Nords and their new empire. There will be dragons..and much more, much more than ANY of us can speculate reasonably. I just dont like how you labeled it: the games are *incredibly* different, as are the final events. You mostly seem to be describing every RPG EXCEPT elder scrolls.
Also keep in mind: Mortals are alternately cursed or blessed by the other daedra. They were tricked, trapped there, by the young prince Lorkhan to become the mer and men we know today, after a time. So yes, in a very clear and direct way, you are destined for this.
Take a deep breath, remember 'Skyrim is not Oblivin is not morrowind is not daggerfall is not arena" and you will be MUCH happier. Because, just like all of us, we have no idea whats gonna happen, and wont until February.
