It's possible, but how do you explain the fact that you then spend a large portion of the game fighting the dragons?

I'm not so sure about that. I mean, the dragon at one point turns around and fus-roh-dahs the player at almost point blank range.

I'd say it's more of fate than help from a dragon, although it is confirmed that you can call upon a dragon for aide later on in the game...

Could be, maybe it's like a Harry Potter thing where a dragon has to kill Dovahkiin, or else he was just be "reborn"?

And the player still lived, seems more like a stun shot to me rather than an out right kill.

Yes

Look, if you paid close attention,after he landed on that rooftop, the dragon kinda stood still and looked down directly at you for a good 5 - 10 seconds before calling the meteor storm.

Maybe he was trying to recognize you somehow?

And also, when the Imperial Legion[your enemies at the time] is ganging up on him at some point, and the PC is caught amidst the trouble, the Dragon fus-roh-dah's you really far away, when he could have just burned you like everyone else.

What tangled webs we do weave.

Incidentally, did anyone notice that Ulfric Stormcloak

Any assumption is legit right now as long as it's not just flat out ignorant.

The whole thing was interesting. I have several questions in my mind that can't be answered until the game is beaten.

So ... maybe that's the dragon that befriends us later on?

It's pure speculation, but that would be my guess, he's gonna remind you later how he saved your sorry [censored] from the executioners axe.

i saw that also^

Hmm, would be cool if he helped you. Did anyone pause to read the book in the leak? The bit at the end?

You are Dragonborn.. you have the soul of the dragon, so fate (ie. Alduin) intervened because you were important. Maybe there's more to Dragonborn than just killing dragons... Alduin wants you alive for some divine purpose?

I don't see it that way, otherwise why does Alduin not call off the dragon's for the rest of the game, no, Alduin definitely wants the dragon born dead because he/she is a threat.

I think Ulfric called the dragon who says you have to yell it for it to work...... besides he stairs at you afterwards kinda awkwardly

Perhaps to challenge Dragonborn, prove his worth...?

I'm kinda thinking it's similar to Morrowind where even though Dagoth Ur was responsible for a bunch of Ash Creatures attacking you, he still had a relatively peaceful conversation with you at the end. I wouldn't argue that the Dragonborn isn't a threat to dragons but that there's more to it than just kill all the dragons. I think it's either:

1. Dragons can absorb your soul like you can absorb theirs, so Alduin doesn't want the Imperials robbing them of it. As to why he spared you.. he was saving you for dessert.

2. Alduin needs you for something, more specifically he may need you juiced up on dragon souls, which is why he sends dragons to you.

3. Alduin came to kill you and got distracted.

"I must destroy the only being capable of stopping my goal to destroy mudus and break free of this accursed plane of existence. Ah I see him, die foolish mortal! Wait what's that? Ohh shinyyyy."

Anyway there are 3 possibilities :
1. The stormcloak leader called it here. Took a while seeing as the dragon was with his lady friend in the hot tub.
2. Other gods (or fate/elderscrolls) directed a dragon (with the mouth watering smell of eggs and bacon) here to saved the dragonborn. Alduin will have very hash words to say to the poor dragon when he learns of this.
3. Dragon is Ysmir's avatar, depowered but still fully capable of summoning Meteor.

I like the sound of option 2 but i'm pretty certain that was Alduin

OR: it's all just coincidence orchestrated behind the scenes by Talos.

The dragons came because the civil war started. Dovahkiian got away because it's the beginning of the game.

We already know that at least one dragon is not an enemy. So there might be a faction of dragons (a tiny minority) who sides with the nords and the Dragonborn.

That dragon is most definitely Alduin. It is identical to the CE statue of him.

I believe this:

Well, we have already seen how the Dragon companion looks. He was purple, this dragon is black.

And no its not Alduin I don't know where people are getting this from, we aren't going to see the big bad guy at the very start of the game.
He looks nothing like Alduin other than he is the same color.
