After a cutscene you will find yourself in a wooded area known as the Evil Forest. Here you find out that Princess Garnet was also thrown off the Prima Vista from the impact. You are also taught about ATE (Active Time Events) which will show up plenty of times throughout the game. To access an ATE, simply press select on your controller. Activating the ATE will show you Garnet and Vivi running away from something.
As soon as you have learned about ATE, it is best to save your game. Once you have done so, move onto the next area accessed through the large tree trunk. There is nothing special in this area, but to make the upcoming events easier, it's best to train Zidane to at least level 5. When you are happy with his level carry on to the next screen.
On the next screen you'll first see Vivi backing away, and instantly you'll be able to tell something is wrong. Steiner happens to be here now, shouting at a strange looking creature from the forest. You'll be thrown into battle.
Prison Cage
- Items to steal: Broad Sword, Leather Wrist.
You'll notice Zidane is now flashing pink. Here Trance is explained as something "induced by a surge of emotion", and it raises the power of that character for a few turns. When Zidane's gauge is full, note that where Skill once was is the ability Dyne. After a few attacks, however, Prison Cage leaves with Garnet still trapped.
It's now taken Vivi! Now's the time to kill it!
Make sure when attacking you are only attacking the lower half as otherwise you will hurt Vivi. And also steal that Broad Sword for Steiner while you're at it, before attacking Prison Cage with all you've got. You will notice that Prison Cage will also sap HP from Vivi. Make sure to use potions on him and not Prison Cage.
Before dying, Prison Cage will emit a gas that causes Vivi and Steiner to fall asleep.
