So I wandered out to Japhet's Folly, and this quest popped up. No dialogue or anything. Just appeared. So I figured "What the hell, bored of walking, I'll do it". Went and cleared out the tower, killed the target NPC, and when I was told to go to report to another NPC, She (or he, kind of a feminine name) isn't there. There is also no descriptor text of any kind on the quest.
Now I'm stuck on this gods forsaken rock by invisible walls and unable to fast travel away. What's up?
