ah that sucks, have you done every quest there and got all the items or not?? if you do, i suggest you try and make a run for it. if you dont, i wish you good luck and a lot of patience. even when i had creatwed an inmortal character it took me a while to finish it because there are lots of hostile npc's there and they just keep coming, while in the meanwhile the turrets keep shooting. hinding behind walls is a good strategy
