ok, but this situation will happen before Sargeras is coming, when Argus is appearing in our skyes.
I agree that "Leviathan" biblic reference is more about N'zoth than Sargeras, but Sargeras is letteraly eat stars, look at Aargus... and a "sea serpent" is not the first thing that I link to a creature with "tentacles". Also, serpent also can be a Dragon.
The world lifts her voice in terror, but only one can hear her cries.
Is refered to the Magni scenario... and in that scenario she is in terror but she speak about Sargeras.
"infinite endings and beginnings". Look also something that we can link to Infinite dragonfly and Nozdormu.
Did you remember my theory about the 5 keys are the Aspects? And now with 3 Aspects dead, 2 key remain to switch? Alexstrasza maybe will die in this expansion, and Nozdormu we know for sure that will die.
In the end... I dont say that we dont fight Naga/Azshara... I speak only about the TITLE of the expansion.
Don't have any sense give an expansion a titles about a mid tier boss and not related to this new main treat.
Actually this dont look like expansion about Azshara/Naga invasion, but more about "an aweakening"! :P We face an Old God.
So, in the TITLE I cant see how any AZSHARA or NAGA reference can works... maybe just a suggestion like the old "The Dark Below" that can work for naga and the old god... or like Illidan words at the end of Guldan cinematic.
World of Warcraft: Into the Abyss
World of Warcraft: Dark from the Abyss
something like that...
