Possible Expansions, Well, one expansion in particular... Options

[Captain Hammer]

So, since this is Bethesda we're talking about, let's all talk about the number 1 expansion that you want to be included in Skyrim, based on what we know so far.

What do I want? Simple. The Ruby Throne.

I mean, seriously, the way the game is currently presented, the final big-bad will involve some manner of sealing away Alduin (Akatosh/Auri-Eil, based on your pantheon of choice) and saving the world. So, why not build on that, by, say, using your newfound status as Dragonborn God-Binder to do something productive.

Example of Productive Endeavor: Kick-start the Fourth Empire of the Dragonborn. Alessia did it. Reman I Cyrodiil did it. Tiber Septim, the Divine Talos, did it. Why in Oblivion's Infinite Chaos should the next Dragonborn not have a shot at becoming Emperor (or Empress)?

I know, I know, there's a large degree of difficulty in trying to figure out how an Elf would become the ruler of the very human-centric Tamriellic Empire. One Dark Elf Empress was difficult enough, even though she did get the job on account of her husband and minor son. Let's not get into the problems that most of the human races would have with an Argonian or Khajiit as Emperor/Empress. I'm sure there's a way to get around this. Even if it does require adopting an appropriate heir from a human household and/or being adopted into that household, giving other members the claim on the Ruby Throne.

According to the lore, periods of severe civil war always come at the end of an Interregnum. And it is always the forging and renewal of the Tamrielic Empire that ends such strife. Historically, when an individual controlled all of Skyrim, it was either as a supporter and ally of the Cyrodiilic rulers (the line of Ysgramoor in the High Kingship of Skyrim allying with Alessia and the First Empire), or that person was Emperor (both Reman I and Tiber Septim unified Skyrim behind them before they could conquer the rest of Tamriel).

And besides, if you can whistle up a dragon with a careful shout, who could stand against an army with that in its arsenal. It worked great against the Redguard Crowns at Stros M'Kai, and that was some of Tiber's most difficult opposition.

Like I said, the Ruby Throne.

I. Want. It.

I want a bloody continent and every citizen therein to be ready to acknowledge me as Emperor. . .
Why shouldn't I get a chance to become the Mother-Fu*&ing Emperor of Tamriel as well?

Spoken like a would-be-conqueror! I can understand your reasoning behind wanting the Ruby Throne, but what you are proposing is not an expansion to Skyrim. A campaign of that importance (not to mention scale) could not be handled with anything short of an entire new game!

It would not be as simple as taking your dragon and your army of ‘volunteers’ down to White Gold Tower and plopping down on the chair. You would have to recreate Tiber Septim’s (and presumably Reman I’s) efforts at subjugating the rest of the Empire. That means campaigns in High Rock and Hammerfell, a siege of Orsinium, a massive naval battle that prefaces your effort to retake the Sumerset Isles, and wars in Valenwood, Elsweyr, and Black Marsh (not to mention Morrowind). . . all with one measly dragon! Though Nafaalilargus was instrumental in subjugating the tiny island of Stros M’Kai, Tiber Septim still needed Numidium to achieve victory in the Sumerset Isles and, presumably, the other provinces. Where’s your Numidium? After what happened to Zurin Arctus I doubt very seriously that you could rustle up someone else stupid enough to give him/herself up for your cause.

Even if you leave those tasks until you can consolidate power in Cyrodiil you are still left with a task that might be impossible to accomplish. Let’s say, for the sake of argument, that Skingrad, Chorrol, Anvil, and the rebuilt Kvatch are all willing to bend the knee (fat chance). We are still talking about laying siege to Leyawiin (which after 200 years has probably been reclaimed by Black Marsh), Bravil (which is probably a province of Elsweyr), Bruma (which owes fealty to Skyrim), and maybe Cheydinhal (depending on how much of Morrowind remains). Accomplishing this with an army of volunteers and one dragon that you can’t afford to feed seems like a daunting task to say the least, and not one that could be accomplished within the confines of an ‘expansion’!

Now, if we're talking about Elder Scrolls VI: Conquest then I'm all for it!
