Outside the ruins there was still no sign of my buddy Ono, so I headed back towards the orc settlement and quickened the pace as I saw spell-cast lightning arc in the darkness up ahead. On the road I passed a pair of the charred vigilant remains and was correct in guessing what was attacking the settlement. Another Volkihar vampire. Ono was here, aiding his kinsmen in the battle but after a long struggle only he and I remained. The rest of the orcs here were now either rotting corpses or ashes blowing away in the wind.
We decided to get out of there ASAP and tracked down the second part of the forge key in an easily accessible shrine. The third piece was much harder, being in the depths of Radthalbar. On our descent through there we got attacked by a pair of dwarven spheres right in a hallway with helicopter blades. Being fleet of foot I dodged out of there easily, but the spheres and Ono were shredded into pieces.
This was all that's left of them.
Found the key part past more falmer scum then decided to head to Fort Dawnguard to hand in stuff since I was in the area. There the newbie Agmaer asked if he could come along to get some experience since Isran didn't seem to be sending his troops anywhere. With Ono's fresh demise in my head I reluctantly said yes. The final 4th piece of the key was fortunately easy to reach but the "lock" itself was in some ruins guarded by bandits. The poor guy got thrashed pretty badly and it was soon evident it would be up to me to take them down.
Suddenly the bandits turned their attention to new opponents behind us, a pair of Volkihar vamps with an undead legate in tow (in broad daylight). THE HELL? Grabbed Agmaer and hauled him to cover while the vampires ate the bandits (I assume, because I didn't see them anymore) and soon enough they were coming for us. Katria then suddenly appeared with her ghostly bow and drew their spell fire. She could surprisingly take their hits while I sniped them off from a safe distance. I guess ghosts beat vampires then?
