Sort of. Ran this dungeon yesterday and when I finished loading in upon exiting the dungeon, I was being attacked but was able to role away and run for it. But they were just normal NPCs, don’t know if it would be the same if a named NPC would have been there.
I also were just yesterday there (Freya Questline, which the first time for me does not work, no dialog options other than goodbye, will try again today).
As @JamCar says you will spawn in midst a fight of two or three fighters and some archers firing, be prepared to run. I had the misfortune to had Kisthis Fleshtearer among the pack who lands two hits before I could escape with 4 or 5 health left…
