The Legend of Zelda: Phantom Hourglass/Isle of Ember

The Ocean!
Now that you're out on the open ocean, you can navigate around and travel to the various islands scattered on the map. To move around in the ship, touch the Feather Pen icon and draw a route using your stylus. The ship will follow this route. While the ship is moving, the stop and go buttons on the left side of the screen will make the ship stop and go, obviously enough. Tapping any part of the screen that is not occupied by a button will move the camera in that direction, relative to the ship. The up arrow button at the bottom of the screen makes the ship jump. This is only generally useful for avoiding sea traps.

Looking at the map, you will notice a face and a ship floating around. The face is Beedle's ship, which is a traveling shop. Once you get a spare 500 Rupees, visit him and buy the Wisdom Gem he's selling. The ship belongs to the Guard, who we will visit later. If you decide to visit these ships, make sure to draw your route so it ends right on the ship. This will ensure that the destination ship won't move while you are sailing towards it.

The Isle of Ember
For now, set sail for the Isle of Ember, making sure that your route ends on the anchor shown on the map. After disembarking, enter Astrid's house up the steps. Once inside, head downstairs. When the door closes behind you, kill the Octoroks that appear and approach the locked door. When Ciela tells you to call out to whoever is behind the door, you can either actually yell or simply blow into the microphone. Now that you have Astrid's attention, you learn that you have to unlock the door. The plaque next to the door mentions something about torches.

Head outside and enter the house to the right. Note that there is a torch in this house, so mark the location on your map. Then read the journal, which tells you to head to the east side of the island. So head east, defeating enemies along the way. Ignore the electrified door for now and make your way to the very eastern tip of the island. There you discover the body of Kayo, Astrid's assistant. He tells you that the three torches on the island are the key to unlocking the door. Mark the location of the torch right next to you on the map. Circle around to the north edge of the island.

Along the way, you'll encounter a yellow electrified gel monster, known as a yellow ChuChu. Do not attack this with your sword, or you'll receive a painful shock. Ignore it for now, as you don't possess the means to kill it. You can push it away with your shield if it gets too close. The third torch is up at the northern edge, so mark it on your map. Now head all the way back to Astrid's basement.

Approach the plaque and tap the three torch locations on the map to release Astrid. After she tells your fortune, she says to go to the Temple of Fire. Talk to her again, and she'll disable the seal on the electrified door you passed by earlier. Head over there and tap the door to open it. Work your way up the volcano, staying away from the shadows of falling rocks.

You'll reach a sealed door flanked by two candles. Make Link face one of the candles and blow into the microphone, then do the same for the other candle. Before entering the temple, though, head left and up the ramp to a chest with a red Rupee in it. Now, enter the temple.
