So as we descend into the tomb the architecture of it is mainly elven, because it was the temple of Elune. But at the Maiden of Vigilance it shifts sharply into very characteristic Titan architecture. The style suggests that it was built even before Aegwynn sealed away the Avatar of Sargeras in it.
That got me thinking. What was the Titan Tomb's original purpose? It seems like a holding cell for something, or parts of something bigger. Especially the room with the Avatar of Sargeras. The machinery that holds him was clearly not designed by Aegwynn. Also it is intresting to note that the area beneath the Avatar of Sargeras is a hollow cave of some sort, like there was something before the legion or Sarg felled it up.
My theory is that it was originally built by the titans as the prison of N'zoth and the thing that was holding the Avatar may have been a shackle for just a part/tentacle/thingy of N'zoth.
It may very well suggest that the image of Aegwynn is indeed the projection of N'zoth or at least the imprisonment of the Avatar of Sarg was part of N'zoth's plan to bring back the legion ages later to help him escape by using the pillars of creation. The pillars may even be keys to the Old God's prison, and by using them we are unleashing the full power of an Old God on Azeroth, unlike the half conscious C'thun or the imprisoned and tightly held Yogg'Sharon we might face N'zoth at it's full potential in the future.
So what do you think?
Is it even news? or am I late to the Tomb specualtion party?
