They're involved in a quest and move between several locations. When they're in a shack near Dondril, Dondril filter doesn't apply to them, and they start saying HAVE YOU NOTICED, FOR ALL ITS PROCLAMATIONS. Instead of adding a new latest rumors entry, making them nolored would make more sense.
So I wandered across Anbarsud not being at all aware there was a quest attached to it. I went inside, looted as I would any other place I came across with enemies, went pretty well as far as I could without encountering locked doors or pits of no return, and went back through the entrance. I come outside and Eraris Verenim is there to ask me to help him. (if he was there before, I didn't note it at all) I accept, not realizing he has an area he's not meant to leave.
Disclaimer: I haven't played this quest. I noticed this discrepancy based on a lucky find while modding and I present the consequences based my knowledge on how the game journal works. If I'm mistaken and it's working as intended, then we can close it & I'm sorry.
