Just started the quest, New Allegiances in Skyrim with the Dawnguard DLC, and Vingalmo has told me to turn Valindor into a Vampire. He says that Valindor can be found in Riften, but when I select the quest in the start menu, there is no Quest-marker for the NPC and when I searched all through Riften, there was no sign of him.
I tried looking up a walkthrough for times he'd be wandering around which places, and he never showed. Could this mean Valindor has died somehow? Or is it perhaps a bug? Is there any way I can fix this?
