Serana is a Nord vampire, you can found her inside a sarcophagus in Dimhollow Cavern. She is the long lost daughter of Lord Harkon and one of the pure blood vampires that is known to exist in skyrim, pure-blood vampires are characters who are granted the vampirism disease directly from Molag Bal, Molag Bal is the creator and patron deity of Vampires. Serana got her vampirism disease through a ritual in which members of her family pledged themselves to Molag Bal.
And the more important is that she is in possession of an elder scroll. Serana will recognize if the player is a vampire or not and she will ask you to take her to Castle Volkihar. And at the end of the Dawnguard quest line, after you defeat Lord Harkon, she also can turn you into a Vampire Lord. She has a unique ability that prove to be useful in some matters, she can transform any elven arrows in that you have and change it into Bloodcursed Elven Arrows and that can only happen if you already obtainined Auriel’s Bow, regardless of which side the player favors.
Serana a unique character in Skyrim Dawnguard
Dont you know that Serana is different from any other character or NPC in Skyrim dawnguard?, unlike other NPC or regular followers, serana shows an advanced behavior and also a unique situational awareness. For an example she always wears a hood when she is outside during sunlight hours. And she also like to comment on the weather, whether its raining or its shining spotight of the glory sun of skyrim she always has a comment about everything, but its typically a blunt complaint come out from her mouth, but its nice though its make her character more live like, and also likeable.
Serana can also interact with her sorroundings very well. If the player is sitting Serana might sit next to you, or just walk around doing something, and its feels so live like, serana is a strong character to be with in skyrim dawnguard, and not just that she alsoe even interact with workstations that is available in Skyrim, like a grindstones, forge or alchemy lab. Even mining in a nearby ore vein, despite not having a pickaxe in her inventory.
Additionally, once you finished all the Dawnguard questline, serana still can continue to serve as your follower, but serana does not have the same set of the usual Follower commands that other followers have. Well, since serana cannot be killed, it would make her a very valuable ally. And if you want serana can also be asked to bite you, and this will grants the ability to become a Vampire Lord, however this particular thing cannot be done if you already asked her to cure herself of vampirism.
There are also fans out there that made a petition about including the option to marry serana, it was going very well. After less than three days of this petition being around, over 1,000 people have come together to sign it. And Bethesda is aware about the marrying Serana situation, but right now there is not sign that bethesda will put a patch or something to make Serana is open for marriage, maybe because Bethesda dont really want her to lose her personality and make Serana have the same dialoge as the other broads that you can marry. It would feel like we are destroying Serana’s personality.
But who knows if Bethesda really considering the option and will make her available for marriage, maybe they could add some unique options and additions to the already lovable Serana character in Skyrim Dawnguard. And they might give her unique dialogue that is consistent with her personality. But i say its not a big deal.
Serana can always be the girl on my side…
