You are having a hard time understanding the lore but insult me? And that is nothing I said. This seems to be the crux of the issue. It isn't just a langue barrier issue. You literally put words into other peoples posts when you read them. The Dragon Soul was not used to create the Twilight Bastion. It has nothing to do with the Dragon Soul being not being called the Twilight Dragon Soul.
If you haven't even played the Expansion and experience its story you can't claim to be an expert. This seems to be why you think the Dragon Soul was involved in the entirety of Cataclysm rather then just the last patch.
The Dragon Soul was not the central theme of the story of Cataclysm. It was the central theme for the last patch where we defeated Deathwing. I have never said that the Dragon Soul was not a part of the story. It being present for one part does not make it present for all parts.So basically when bad guys are greatly affected by an item which could destroy their group doesn't make it part of their concern or is central theme to the story? Which is which...
So where is the lore to say that the Dragon Soul was in the possession of the Emperor of Pandaria? How did it escape the mists when little else did? Why did the Night Elves give up control of the Dragon Soul when they used it to create the barrier around their city? How did those two manage to use the same object at the same time to create their barriers? You have yet to provide one shred of lore that supports your claim that the Dragon Soul was involved in the creation of their respective barriers.These are the kind of answers coming from someone who is shortsighted and lacks understanding.
The Dragon Soul being involved in the Sundering does not make it involved in the creation of Barriers.
