But, I believe I have found a bug, and if I'm right it's a serious one.
I fought my way down to the Radiant Guardian, and killed it. Then I got infected by Toszylae, and then killed him. I made my way back to Ulirfendor, who told me to go see Talion, but to make sure I killed Toszylae first. Well, I though that was a bit odd, since I had already killed him, but I thought (or perhaps just hoped) that it was no more than a minor dialogue issue. But now I have talked to Talion, and the only option I have at the end of the conversation is "No, I have not killed it yet". Well, I could fight my way beck down there, but I assume that Toszylae is unique, and therefore will not be there. If that's the case, I can't complete the quest, and have a permanent does of rotworms (As an aside, when searching the forums about this I discovered that I needed to walk over his corpse to get a helmet, which I didn't do, so I have to go back down anyway. I would rather get cured of the rotworms first though!)
At first I though that maybe I had messed up with my save games, but I have the Demon heart in my inventory so I am sure that's not the case.
