One of the new features introduced in Final Fantasy XIV: Heavensward is the ability to fly around Ishguard. Those interested in flying around the vast land of Ishguard will first need to obtain a flying mount.
The Black Chocobo is the first flying mount you will get in Heavensward. However, you won’t be able to fly until you complete a couple of tasks.
Getting the Black Chocobo
Upon finish the quest, “Divine Intervention”, you will get the Whistle to summon the Black Chocobo. This quest is part of the main storyline, so you’ll eventually come across it.
The Black Chocobo, like all other flying mounts, won’t be able to fly right away. To unlock flight you need an Aether Current, which is needed to control their direction in the air.
Upon getting the Black Chocobo Whistle, you will learn that you will need to unlock Aether Currents throughout the six areas of Ishguard. Unlock all of them and the Chocobo will be able to fly.
Before you can unlock an Aether Current, you will need to use an item. You can get the Aether Fragment through quests.
Using the Aether Compass
To help you find the Aether Current around Ishguard, you will need the help of the Aether Compass that you got along with the Black Chocobo Whistle. Use the Aether Compass from the Key Items menu and it will tell you what directions you can find the Aether Current.
As soon as you are able to find the aether currents in an area, you will be free to fly around.
