I finished the Dark Brotherhood quest line long ago. Sometime after that, I noticed Naryu Virian pop up in Saint Delyn's Canton. I talk to her, she gives me a warning, but there's no quest involved as far as I can tell. Then she goes away for a long time. After being away for months, she suddenly pops up again, gives me the same warning, still with no quest involved, then goes away for a long time. After a while, she comes back again, and the whole cycle just keeps repeating. Am I supposed to be doing something to trigger a quest, or is this just an annoying "atmospheric" behavior on her part? Is it supposed to be hinting of something to come, or what?
I've fought mudcrabs more fearsome than me!
