So I've been thinking about the Dragonborn questline, which is a bad thing, because the more I do, the less the actions of the antagonist, Miraak, seem to make sense.
For those of you that haven't played Skyrim's last DLC, you venture into Apocrypha via Black Books scattered about the island. If you die in Apocrypha, you are just spit out of the Black Book and get to try again, rather than getting a game over. This isn't just a gameplay mechanic. It's integrated into the story, with Miraak having his Seekers kill you when he first meets you and sending you back to Solstheim.
So if dying is all it takes to escape Herma-Mora with your life, why didn't Miraak just kill himself?
I'm assuming he didn't because he entered Apocrypha via a different means than we do, and thus killing himself would just mean he'd be dead with his soul permanently trapped in Apocrypha. However, we do find a Black Book that leads us right to him in his Temple, which might mean that's how he escaped Vahlok.
Moving on from that. Later, it's revealed that Miraak needs to absorb your soul in order to escape Apocrypha. What exactly is so special about your soul that he needs it to escape Apocrypha, vs all the other Dragon souls he has at his disposal or may steal from you? Also, if he needed your soul, why would he have allowed his Hive Mind to send Cultists to try and kill you in Skyrim, where he'd have no chance to absorb your soul?
Also, how did he start ensnaring minds on Solstheim again, and how did he manage to get a dragon that was under his control out of Apocrypha/Take over a dragon that wasn't living in Apocrypha?
Even more importantly, if Miraak needed your soul, why didn't he just kill you right when he meets you, rather than just sending you back? He risks letting you grow in power by letting you leave, and it's not like he needed your help to get dragon souls. He has a dragon insta-kill Shout!
Lastly, if dying in Apocrypha isn't really dying, but just getting sent back to Nirn, then how exactly is Miraak going to be able to absorb your soul if he defeats you?
Can anybody fill in these plot holes for me?
