Found the problem
I'm afraid the quest still
Odd,
It's impossible!
I don't know whether or not it is a bug since I've never played Morrowind in another way, but as soon as I attack Feruren Oran I get several people attacking me (from another floor!), not to mention that evil-looking son of a- which insists on interrupting the fight with asking me for gold, telling me I'm free to go, only to make me find out I am free to go somewhere else - and with a lot less stuff.
Is it a bug? I can't defeat 5+ people including a guard.
i have an another
i have an another problem.Ethasi Rilvayn is absent in Morag Tong Guild in Balmora. There is only a guard in there. Is this a bug? Am I doing something wrong?
What naughty thing did the OP
I didn't have any problems
I didn't have any problems getting the Oran writ, but I did have the same issue as Zadama after killing him, used the console to update the quest and no more problems like it.
As far as people being attacked by everyone in the room (for that writ and others), every time I've been attacked by someone that I clearly remember not getting involved in the original quest I've been able to end the fight by yielding to them. So far. Hope that helps someone.

Ill take a look
