I enjoyed the DLC, but didn't put as much thought into it as some of you have. Skyrim is my first Elder Scrolls game, so I'm not as familiar with the lore throughout. I have wondered about the Dragonborn who leaps into existence as a result of Dragon Aspect. Who is he? Whoever he is, he puts Miraak into a world of hurt, if he gets the chance.
It's assumed to believed to be the second dragonborn.
But how did he come in contact with the second Dragonborn if he was locked away in Apocrypha?
He wasn't always in Apocrypha, just sometime after he was about to be killed.
Also I believe Miraak was the First "recorded" Dragonborn in history and there might have been way more before him, we wouldn't really know.
Because Miraak was not on Nirn. He is in Apocrypha. Not once is Miraak on Nirn at all. His spirit comes and goes, stealing souls from you, but remember. The greybeards aren't as wise as they are made out to be. They don't know everything. Just meeting you was a first time for them to ever meet a dragonborn themselves. They are not immortal. It's not a plothole unless the greybeards were involved with the DLC which they were not. They said they didn't know if there were other Dragonborns which was very possible. The Dragon blood has been around since forever.
Where do you see a plothole?
^
That point where he is able to come and go as he pleases, stealing the Dragon souls Also clears that point up.
Also The greybeards didn't know that you were the Dragonborn, They just called him using that shout, and you happen to answer that call and they test your powers with the basic shouts.
- Much of Miraak's dialogue seems to have been cut. Game data reveals the Dragonborn and Miraak converse longer before the battle at the Summit of Apocrypha takes place. Some of these lines include "I grieve that you must meet your end this way but necessity demands it.", "You..You are the true Dragonborn.." and "Well fought, Dragonborn, but I'm afraid this is not over. I shall return and take what is mine." This suggests that another battle was to take place or Hermaeus Mora does not kill Miraak and he escapes.
Here's an extract from Elderscrolls wiki, the official one.
Which suggests another appearance from him?
To be fair, much of Miraaks past has been shrouded or hidden. Possibly because of his ties with Hermaeus Mora and perhaps his true history is hidden in Apocrypha.
Also Apocrypha is a place for hidden knowledge, which could have led to him being able to discover how to create his own shouts.
He does use a special four word shout too, now isn't that odd?
Miraak uses a special four word shout that allows him to kill a dragon instantly, absorb its soul, and heal himself. It is the dragon's name followed by "ziil los dii du!", which translates to "[Dragon's name], your soul is mine to devour!" The shout has an ID of DLC2MiraakFakeShoutSpell and is called "Marked For Death - Krii." This is unusual, as most phrases or shouts in Dragon Language are made up of three words.
- "You have no idea of the true power a Dragonborn can wield!"
