I'm just wondering. Akatosh is leader of Nine Divines, he is also the only one with any real power as the rest are lesser deities, and one is even an exalted human. Basically Akatosh is the glue that holds the divines together, and protects them and the world form the Daedra. But now we're finding out that Alduin is Akatosh's alter ego. Now the leader of the Nine Divines, and the true source of there power, has turned evil and is their enemy. Will the Nine Divine be able to survive this? Is it the end of the Aedra as masters of the world? Will the Daedra be able to take over again after the events in Skyrim? It's all very confusing, and it leads me to believe that maybe all the gods are unstable, or that none of them are actually good at all. What do you guys think of this whole mess. :shrug:
Your questions stem from a string of misconceptions. Akatosh is not the "leader" or the glue that holds them together. The Nine Divine is not a traditional religion. It's all really complicated and it's too much to get into here.
In short, Alduin is not really "evil," the Aedra are trying to escape Mundus because it's viewed by them as a trap created by Lorkhan. Akatosh only seemed benevolent to the Imperials because that is how they view him.
Thinking whether or not the Aedra are "good" or "evil" is a matter of perspective, or just entirely futile in itself.
Hopefully this will answer some of your (OP's) questions and clarify some of the misinformation that was given. From the book The Amulet of Kings: "On behalf of the suffering human races, St. Alessia, the first in the line of Cyrodiils, sought the aid of Akatosh, the Dragon God of Time, and ruler of the noble Aedra. Akatosh, looking with pity upon the plight of men, drew precious blood from his own heart, and blessed St. Alessia with this blood of Dragons, and made a Covenant that so long as Alessia's generations were true to the dragon blood, Akatosh would endeavor to seal tight the Gates of Oblivion, and to deny the armies of daedra and undead to their enemies, the Daedra-loving Ayleids.
In token of this Covenant, Akatosh gave to Alessia and her descendants the Amulet of Kings and the Eternal Dragonfires of the Imperial City. Thus does Alessia become the first gem in the Cyrodilic Amulet of Kings. The gem is the Red Diamond in the middle of the Amulet. This is the Symbol of the Empire and later taken as the symbol of the Septim line. It is surrounded by eight other gems, one for each of the divines.
So long as the Empire shall maintain its worship of
Akatosh and his kin, and so long as Alessia's heirs shall bear the Amulet of Kings, Akatosh and his divine kin maintain a strong barrier between Tamriel and Oblivion, so that mortal man need never again fear the devastating summoned hosts of the Daedra Lords.
But if the Empire should slacken in its dedication to the Nine Divines, or if the blood of Alessia's heirs should fail, then shall the barriers between Tamriel and the Daedric realms fall, and Daedra-worshippers might summon lesser Daedra and undead spirits to trouble the races of men." Bolded portion by me. The Nine Divines are Akatosh's kin, not necessarily his inferiors. The "religion" Velorien puts it isn't that complicated for discussion here.
My only suggesiton is, if you have Oblivion, go back and read the books in the game. There is more than enough lore there to provide an understanding of what was and what may be in Skyrim. :tes:
