Elder Scroll (Sun)

[anonymouselbow 0]

So, I discovered Serana and didn't kill her immediately, dialoguing and such and lead her outside.  But it was in the afternoon and she was complaining about the sunlight so I entered some nearby dungeons and she got herself killed.  Examing her body I could not take the Elder Scroll but I found the command to add it to my Inventory.  I'm guessing this is a unique item so my concern now is about the Elder Scroll that is still visibly strapped to Serana's body and what if anything I should do about that.

You broke the Dawnguard  quest if Sera a died. You can't complete Dawnguard without her.

That's okay.  I'll see whatever happens with my choices and then I'll try again with mods installed at some point.

Unfortunately essential NPCs seems super important setting, because I think I just broke another quest when I cannot report back to Adelaisa Vendicci because she was killed in the assault somehow.  Is there any method to complete quest objectives through console commands?
