When you killed the opponents in the fortress, you met Bahasha the soothsayer. He said that Brigade General Tahabata could ruin everything, and that you needed to get him out of the way. You then defeated Tahabata and conquered Tiamat's Fortress. However, you were unable to the find entrance to Tiamat's Shelter. Suddenly Garnon appeared and said that someone had revealed to her the secret of entering the shelter. Kahrun said that he would enter Tiamat's Shelter instantly.
