- interspecies and gay marriage is allowed (you can be a lizard guy and marry a werewolf dude if you want)
- you can kill things by yelling at them
- you can punch bears
- you can secretly shove 100 potatoes in someone’s pocket
- there are lizard furry porn books scattered all across the place
Well, THIS will give you the quick and dirty rundown.
To sum up, basically the original Dragonborn, Miraak, is trying to return to the land of the living to take over the world. You travel to the Morrowind island of Solstheim, and go through a number of new quests, meeting new people, with new shouts, spells, and the like. For me, the big draw of Dragonborn is Hermaeus Mora’s Black Books, which give you some fantastic new abilities. Also, you can tame and ride dragons, which is kinda cool even if the control scheme is pretty weak. Overall, I’d recommend it, just for the opportunity to explore Solstheim and get your hands on some of those new abilities.
It is definitely implied they have a strong bond beyond most of the Dragonborn’s questing partners! And yes, Serana is undoubtedly one of the most badass females in the game. Even with the Interesting NPCs mod, Serana is pretty high on the list.
