ok, so, im pretty happy right now, because i managed to find "drascua" the hagraven carrying the pommel. somehow, luckily, i managed to glitch under the map using a platter and whirlwind sprint. and as it turns out the hagraven is, actually underneath the map for some reason. shes in bewtween two rocks in a total unreachable place, but i got to her ! haha. i had to shout my through the platter and through the rocks, then again once more to finally get to her. i checked on elderscrolls wiki, it says you did actually bug the quest by clearing the place before getting it. but i did get it !
