I'm totaaly stuck in the main quest at the moment. In the legend lost quest I'm being sent to the College librarian but I get no reference to the scroll in the dialogue box. i have one scroll (blood) but apparently this is not the one needed. This also gets me stuck in the Dawnguard quest. In the mean time I have finished most of the side quests except the civil war quest so now I'm sort of unemployed. Does anyone know a solution?
