In Skyrim, after finishing the main questline for the mage's college, the Dragonborn can help Arniel Gane replicate the disappearance of the dwemer. When Numidium was destroyed, the dwemer disappeared along with it (I mean, they had already disappeared when they bound themselves to the brass robot). It's long been believed that the dwemer bound themselves to Numidium, a divine being, in service. Lastly, we have proof that the Dragonborn is divine with the disappearance of the dwemer (of all things). Given all that, you can see how it's likely Miraak's rebellion is the entire reason the Last Dragonborn was sent by Akatosh. The Last Dragonborn is basically written to be the same way, only they decide to do the right thing and go ahead and save the asshole-world anyway by stopping Alduin and ending the cycle.

The people during Miraak's time probably treated him like the scum on their shoe, while the dragons were the only people who were nice to him, and the daedra stroked his ego. How many players eventually go crazy and slaughter a town? I know I've wrecked the Thieves Guild and reloaded a few times over the years. They treat the Dragonborn like crap, constantly insulting her, trying to kill her, and trying to rob her. Most people in the world of Elder Scrolls are straight-up unapologetic jerks. Honestly, after playing Skyrim for years, I. I will post an update once I find out.We learn in the Dragonborn DLC that Miraak, the first Dragonborn, didn't do his job and decided it would be better to join with the dragons. However, I do not know if the Dawnguard allow you to keep that ability, since I haven't gotten that far along in the questline. So for those of you who actually wanted to join the Dawnguard but didn't because they wanted to become a Vampire Lord, you can become one and still join the Dawnguard. The only difference is when along the questline you become one. So, regardless of which side you choose, you can still become a Vampire Lord.

So, if you sided with the Dawnguard, then once you open the portal to the Soul Cairn, Serana tells you that she either has to trap some of your soul inside of a soul gem to allow passage into the Soul Cairn, which would slightly weaken you, or she can turn you into a vampire to allow passage, which automatically allows you to become a Vampire Lord. In addition, you can't enter the Soul Cairn unless you're one of the undead. While many of you probably already know this, but for those of you that don't, you will be entering the Soul Cairn regardless of which side you choose.

One thing I'm guessing is that a lot of people are choosing to side wi the Volkihar Vampires over the Dawnguard because they can become a Vampire Lord.
