I recently noticed that Vampirism was listed as one of my Active effects. I had been fighting some Blood Fiends so guessed one must have bitten me, so I thought I would try vampirism out.
The problem is I can't find Vorundil, having looked all over Rawl'Kha, Riften and Evermore (I might have missed him but I had no quest marker) I asked if anyone knew where to find him. I was advised on the Road South out of Rawl Kha, neear Fort Spinxmoth and near Riften Stables, I can't find him at any of those. I have tried several times with logout out and back in. I am now wondering if I need to do something else to get vampirism or if I have come across a bug.
