Elder Scrolls for Sale*

After completing the final Dawnguard Main Quest, return to the fortification of your alliance and speak to Dexion Evicus, the Moth Priest. You can bring the conversation around to the topic of the Elder Scrolls that you’re carrying. In time, he would like to see them returned to the Imperial Library. You can:

• Give him the Blood and Sun Scrolls.
• Or request 6,000 gold for them, which he’s willing to pay.

Repairing the Castle*

Now that you lead the vampires in Castle Volkihar, you can go about refurbishing this grand dwelling. Aside from the bedroom that you gain (Lord Harkon won’t be needing it anymore), you can also speak with Garan Marethi and request that he clear the rubble from the passage that connects the keep to the courtyard (where the moondial is located). This allows for faster travel through the castle, although the fastest way to reach the Soul Cairn is still to Fast-Travel to the balcony, then step into Valerica’s Laboratory from there.

Serana’s Cure*

Return to Fort Dawnguard and speak with Serana. You don’t actually need to be in the fort to begin the following conversation, but the location is ideal for meeting up with her again. After exhausting any more urgent topics of conversation, you can suggest Serana seek a cure for her vampirism. When she says no, answer with any reasoning you wish. Then (to reaffirm your choice, as this can’t be undone), tell her you’ll support her decision to cure herself. She reluctantly agrees and says she knows of a priest named Falion who can help. She doesn’t want you to accompany her; this is one task she wants to be left alone for. And with that, Serana leaves your company.

It takes at least five days for Serana to trek to Morthal, find Falion, receive the cure, and return to Fort Dawnguard. Occupy yourself with other adventuring during this time. If you check in on Serana by visiting Falion’s House in Morthal, she will be there (as shown), but she still doesn’t want you to intrude into this private matter.

Eventually, Serana arrives back at the fort a changed woman; her eyes reveal how much she’s changed (see pictures). She tells you it’s like the world is alive again, though she seems to miss her old powers. You might, too, as she no longer has any of her vampiric abilities or resistances (or their associated weaknesses), though she remains a formidable wizard.

Valerica’s Return*

Once you’ve defeated Lord Harkon, Valerica no longer needs to remain in exile in the Soul Cairn. Backtrack to the Volkihar Balcony, open the door into her Laboratory, enter the Soul Cairn, and trek back to her location in the Boneyard.

You can now convince her to return to Castle Volkihar (to live with you and Serana as vampires or to start a more peaceful sect within the castle). She will make her way back on her own; you need not chaperone her.

Visit her the next time your adventure brings you to Castle Volkihar, and you will find that she has moved back into her lab and is now tending a garden in the moondial courtyard. Help yourself to any of the ingredient plants in the garden or to the potions in her chambers.
