This is a bug report I have encountered way into the mages guild. Everything has gone wonderfully until edwinna said I should challeng the archamage and I decided I first wanted to do the duty he would give me first. that was easy since I already had all of the three books I needed, the only problem was the location in the name of this thread. I enter into the building, there is no sandstorm or anything that would cause the game to ctd, after the loading screen I get a black screen for two seconds then the game pops up with the elder scrolls oblivion has stopped responding or working correctly, one or the other.
Bottom line, it ctd's so something about the arvsdrelen worldspace may cause the game to crash for more than just me. I'm am making a temporary fix with cs with a second obaladas demnavanni ouside the house to finish the quest then the archmage is going down.

Now I have to speak to yagrum bagarn in the corprusarium and the same issue. I finally find the door to the lower depths to find the guy, and it ctds after it loads the area.
