Thunder Plains and Macalania Woods
You get access to a whole new set of mini-games here in the Thunder Plains that involve ‘calibrating’ the towers. But first, if you told Cid “You bet I do!” back in the Zanarkand Ruins, walk a short distance east from the 
Save Sphere and look for him sulking. He’s not hard to spot because he’s marked by a large purple 
on the mini-map. If you answered “Not really.” he isn’t here this chapter; you’ll find him on the Thunder Plains in Chapter 3 instead.
Talking to Cid here is worth Story Completion Percent. Speak to him now; if you miss him, this 0.2% can still be earned on the Thunder Plains in Chapter 3, where he apologizes instead of sulking.
The only other things to do in the Thunder Plains for this chapter are the Tower Calibration mini-games and collecting the treasure chests. Speak to the Al Bhed man near the first tower close to the Save Sphere, and he’ll give you a brief introduction to calibration towers. The maps identifying where each tower and treasure chest are located can be found below. You can learn more about the mini-game using the link below:
Side Quests
Yuna, Rikku, and Paine all have different tower calibration mini-games to play at each of the 10 lightning towers across the Thunder Plains. This page provides an overview of the games and the rewards you can receive.
Worth noting is that the Tower Calibration mini-games do not offer any Story Completion Percent and aren’t required to get 100% Story Completion. However, it is worth playing them properly: attempt all ten towers and calibrate at least five of them perfectly, then talk to the technician inside the Travel Agency to receive the 
Samurai’s Honor Garment Grid. Your calibration results also improve the treasure you can find here in Chapter 5.
That’s everything you can do in the Thunder Plains for this chapter. Head to the nearest Save Sphere to warp back up to the Celsius, or, if you’re close enough to it, you can walk north to the next destination: Macalania Woods.

Macalania Woods
Welcome back to Macalania Woods. Walk up the nearby trail (not the shimmering one), and you’ll see Tobli’s assistant, the Hypello, waving and frantically trying to get your attention. Head up, speak to him, and he’ll ask you to help search for the musicians again.
Use the shimmering pathway to travel back to the Spring area where you spoke with Tromell. Here, you’ll find Bayra again. Talk to him, and he’ll explain that he’s having trouble communicating with the rest of his musical troupe. And so begins the next Mission…
Mission: Track Down the Troupe!
This is one of the easier Missions you’ll encounter in the game.
| Musician | Location | Screenshot |
|---|---|---|
| Donga | The first musician can be found by following the shimmering trail back the way you came and towards the Save Sphere. |  |
| Pukutak | The second musician is where you found Donga the last time you were here, on the other side of the Spring, which you can reach by going south at the four-way intersection. |  |
Your reward for finding the two musicians is a 
Haste Bangle accessory. You can also head back to the entrance and speak with Tobli’s assistant to receive another reward. The Hypello will give you the Bitter Farewell Garment Grid.
The last thing to do while you’re here is complete the Publicity and Marriage campaign tasks, which involve speaking to the same two Guados as before:

Use the Save Sphere to head back to the Celsius, then make your way to Bikanel Desert.
