Weyard (ancient past)

Weyard in the ancient past was far different from what it is today. This era in Weyard's history is alluded to several times throughout both games; it is described as the time period when Alchemy was commonplace, and it was at the end of this era that it was sealed away. Fans speculate and hope that there will be a video game or other media property set in this era that depicts that cataclysmic process.

Known elements

 * Alchemy was used to drive civilization in this era. However, it was used for war and was soon sealed away by a group of Sages to prevent worldwide destruction. All the elements below were permanently affected.
 * The landmass of Weyard was much more uniform and in the shape of a crescent moon, with an island landmass to the east of the main landmass. This mass started breaking up and sinking into the oceans with Alchemy's departure.
 * Great civilizations, including a far more grand version of Lemuria, as well as the earthbound city of the Anemos, colonized the world as driven by the force of Alchemy's powers.
 * Poseidon is described by the old man at the Sea of Time Islet as the "once true rightful king of the seas" in this era. Poseidon was evidently a more sentient, gentle being in this era.

History
Golden Sun: The Lost Age provides a general overview of Weyard as it existed in the ancient past; it is the Lost Age of Man that the game's title alludes to. In this age, the ability to use Alchemy and Psynergy was unfettered and accessible to the general populace, and civilization had reached great levels of development. Various clans of Adepts existed across Weyard, and the landmasses of Weyard itself were far more uniform: It generally resembled the shape of a giant crescent moon. The four Lighthouses were lit at this time, providing energy to both the world and the people.

As the story goes, conquest and war eventually became objectives amongst those who desired power, riches, and dominion over all that lived, and global war fueled by the misuse of Alchemy for military purposes yielded potentially catastrophic results for Weyard; the world would have been torn apart if not for the efforts of a group of brave and wise men who took it upon themselves to seal Alchemy away by removing the Elemental Stars from the four Lighthouses, and confining the jewels in the innermost reaches of Mt. Aleph's Sol Sanctum. The world and the people were saved from themselves, but deprived of a massive resource, and Alchemy and the four Lighthouses would remain dormant for ages to come.

With the sealing of Alchemy, Weyard's landmasses gradually began to break up and decrease in size over the ages, though this would not be noticed by the general populace due to how gradual it was. However, over time the populace began to lose much more; Civilization thrives by building upon the knowledge of the past, and the disappearance of both Alchemy and seemingly Psynergy as well caused the various cultures of the world to lose knowledge and become more primitive over the ages. That is why in the current age when the Golden Sun games take place, Weyard is a fairly inactive and sparsely populated world, with scarcely few individuals being aware of the existence of the force of Psynergy, let alone possessing the ability to manipulate it as Adepts. A lot of the great Lighthouses, mountain sanctums, and other structures that stand today from the ancient past cannot be properly investigated by today's commonfolk because they lack the necessary adeptness to Psynergy that the locations were constructed in mind with.
