In that case, that's my option for Niernen. A quick blurb in Dunmeris to inform the Ashlanders that the Nerevarine brought monsters back with him from Akavir and that he has betrayed them all. The rest of her arguments will have to wait for later, because she'll probably be overcome by a stress-induced panic attack/flashback (the swirling steam and hulking Centurion triggering a hallucination of a towering Kamal in a snowstorm) and initially not be of much use after that.
