Air's Rock

Air's Rock is a dungeon in Golden Sun: The Lost Age that is traversed so that the party can obtain the Reveal Psynergy. It lies in central Osenia, to the north of Garoh in the middle of what appears to be a large desert. Unlike the Lamakan Desert, Suhalla Desert and Yampi Desert, the player does not enter a non-overworld area as soon as they enter the yellowish-brown area of land (which represents the desert on the overworld).

The name Air's Rock is a play on the real-world Air's Rock, a large fold-mountain in the center of Australia that all the Elemental Rocks resemble to a degree. The real world version now more commonly goes by it's native name, Uluru, however, and does not contain a network of tunnels and caves inside of it.

Air's Rock is the Elemental Mountain of Wind, and most of the puzzles are based around manipulating Air to some degree, and the Psynergy found within, Reveal, is a Jupiter Psynergy. The location is borderline notorious for being the most gigantic and time-consuming dungeon-style location in either Golden Sun game, in spite of it being explored early in The Lost Age.

In Alhafra, if one goes to the top most room of the Mayor's mansion, there is a man the player can talk to who asks if the player can see Air's Rock, and when the player answers yes to his question, Felix automatically walks over to a window, and the game shows the player an overworld view of Air's Rock.

Story
In the town of Garoh, many of the lycanthropian residents have powers aligned with Jupiter Psynergy, and while the player traverses the dungeon they encounter a large Psynergy stone at it's heart, similar to the one located in Vale. After completing the dungeon, the player travels to Garoh where they use their new found power of Reveal to gain entrance to a hidden series of caves underneath the town where they talk to Master Maha, a grand old werewolf who had traversed Air's Rock and gained the Reveal Psynergy, losing his ability to retain human form in the process. In a conversation with Maha, it is suggested that the strong winds eminating from Air's Rock probably carried particles of Psynergy stone to Garoh, which in turn gave the inhabitants their Jupiter Psynergy.
