I'd long known that once you complete Bala's quest in stonefalls, that you can meet her ghost just outside of the othrenis wayshrine. However, I hadn't really given much thought on the matter until I stopped to actually look at the corpse I had seen for ages and didn't understand just outside ebonheart. It seems that that's where Bala drowned herself after whatever news she got from you about the quest. You can actually see her name on the corpse there more or less across from Almalexia's shrine.
