I have just spend several hours and discovered that the 5 statues that should give you clues so you can answer them correctly in Keara HQ is bugged. The statues do not give you the clues which does not ever let you say who they are. I have tried several times just answering the 5 statues correctly but it will not work. I have tried going back through many older saves with no luck. This bug will prevent you from getting an achievement.
