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.
