In the ninth chapter, you find new mountainous and island locations. There also are new opponents here. Eliminate fire birds with water attacks and dark boars with light, or fire attacks. These opponents can speed up their attacks and reset charging of yours. Additionally, there are horses here and you can attack them with basic blows.
As you fly right, you will find several houses. In the second one, there is Gen and Drust. There also is a small girl - Genovefa - who will gladly join your party, as soon as you kill the boss. Fly right of those characters and fly into the cave that you find. Inside, move the lever, which starts a mechanism closing the door on the left, and opening one on the right. You will have 40 seconds to fly down and move up the wind. As you know, gusts of wind ease down each several seconds. Take advantage of that and hide behind terrain formations. Thanks to this, you will not be knocked back by the wind and make it in time. After you do, you will be rewarded with 2 chests and a stone. To leave the cave, fly up to the very top, move another lever and fly up to the exit.
A puzzle and a boss
As soon as you exit the cave, fly to the right. You will get onto a mountain, where you find a puzzle. In the puzzle, you have to direct light from the symbols with Roman numerals onto the correct spots on the wall. In the room with the puzzle, there is only one symbol. Two more that you need for this puzzle, are on the platform above. You have to stand next to them as Aurora and push them down to the very bottom. The symbol with numeral V has to be at the very bottom, but the one with XIII can be left on the platform above. You will only have to use Igniculus to direct the beam of light to the wall below. Pairs that you have to couple up have been marked in the above screenshot.
Numeral XIII is on the platform above.
After you have solved the puzzle, you will be attacked by the boss. To fight him, use characters that deal damage to all opponents, with a single attack. After you manage to kill the boss, return to Gen's house. She will join your party. She starts with 16 points to distribute. With the new ally, return to where you have fought the boss and travel to the next location.
