Im sorry i just started getting into the Lore and i read somewhere that Akatosh is known as 'Alduin' to the nords. So at the end of oblivion Martin becomes the dragon, so in Skyrim are we fighting Akatosh as a whole?. Not a mix of Martin and Akatosh spirit? and for that matter didnt he just become a statue at the end of all things?

You've got a lot of big misconceptions about what happened at the end of Oblivion. Martin became an avatar of Akatosh, not Akatosh himself. Akatosh did not turn into a statue. Alduin is Akatosh, but the Nordic view of him, which makes him different. If you use the search feature and look around the forums, you'll find a bunch of other topics discussing this same thing.

i think the alduin is akatosh thing in general may be slightly obscure .. i dont feel we will actually be fighting the akatosh i think there may be more to it than akatosh is alduin whos destroying skyrim with his dragon pals, i think they may be a bit more to it

Yeah, tbh I heard on these forums a while back that Beth aims not to decieve the player in any form.
What you see is what you get more or less these days...

However they may have stepped up and changed tactics, seeking to appease some complaints with gamers.
Until Skyrims release however all is speculation and shouts of "hey this is a cool way of looking at it" from posters.

I do hope they've got a few dragons to leap Fonzie style, some dreams to wake from, some McGuffins baked and psychadelicaly ready though.

As I really hope that Alduin is a apocalyptic seismic shift in Nirn that has woken up a bunch of dragons..
Of which the leader is calling himself Alduin looking to mantle the god Akatosh in the form of Nordic destroyer / genitor, whoah flashback.

Edit: It may be me, but the company sounds lovely when you call it Beth.

Actually Alduin is to the Nords what Akatosh is to everyone else. They are not even close to the same thing Alduin is to be feared, Akatosh is not.

Ohhhh, kind of like how Allah is to the Muslims as Jehovah is to Christians?

But in Tamriel as a whole, they are not the same right? If Alduin is really Akatosh, and it appears in TESV:Skyrim as the nords believe it is, then the nords' version of Akatosh is the right one.

No they are not the same at all, just theyre rank as i guess king god among the other gods.

Which was my point, unless I'm reading this wrong. Akatosh and Alduin are both in the same "position" ( can't think of a better word, sorry.).

They are the same. The Nords' version of Akatosh, Alduin, is correct. However, the Cyrodilic Akatosh is also correct. It's complicated, so don't feel bad.

Yeah, Tamriel is a weird place, I once heard the blue fog in oblivion was magic, not really bad choice of color

Akatosh is seen by most races as the creator the genitor of Nirn.
To the elves more so, to the Empire he is the co genitor of the blood line with Alessia.

Alduin is the Nordic aspect of Akatosh, due to their anti Mer feelings and wars Alduin became more hostile to Men.
As the Nords are by far the purest Men rather than Mer or Aedra touched in ways like the Bretons / Imperials.
They venerate Shor / Lorkhan who is the Anthisis of Alduin / Akatosh.

As such Aduin is both the start of them as the large part of Nirns creation, and the destroyer as an enemy of Shor and the prime god of most Mer.

Alduin/Akatosh is hard to understand, but they are the exact same god. In Cyrodiil/most of the Empire Akatosh is revered for being the creator, god of time, and hero to the humans for forming the Covenant with Alessia (what formed the Amulet of Kings). But the Nords view him as Alduin, the creator, god of time, and world-eater. See, Akatosh/Alduin does everything spoken of. He not only created the world, and is the god of time, but he is also the world-eater. The Cyrodiilic Empire ignores this part, whereas the Nords bring it to the forefront, and that's why they fear him. They view him more as the god of the apocalypse.

I think Alduin may be just a presentation of a God, for the Nords, and in fact it appears as a dragon with all the nords nuances, but just for the people/place with faith in it as Alduin. For the faith in Cyrodiil, it would have a different presentation.

The Yokudan god Sakatal is similar to Alduin. Sakatal is the god of everything, but he is hungry all the time, and being the god of everything, the only thing he can eat is himself, thus destroying the world and creating new ones in a cycle.
So you are stuck with a god who is going to destroy the world, but without whom the world would not exist in the first place.
Then it gets complicated.
The original Akatosh existed before the world, and with his formation time started, so the other spirits could take form, as the Aedra and Daedra. When the world, Mundus, was created, Akatosh and the other Aedra had to die to become part of it, separating them from the spirit realm of Aetherius, and being reborn in forms that could be influenced by mortals. In effect, and this isn't lore, just my attempt to explain it, the Akatosh of the Empire, and Alduin, are children, successors, or different states of the original Akatosh, and these different facets are altered in nature by the beliefs of mortals.
