Menardi

Menardi is a Mars Adept who, along with her partner Saturos, functions as a primary antagonist in the first Golden Sun. The duo lead the original effort to break the seal on Alchemy and restore it to the world of Weyard despite its potential to be abused by its peoples, and their efforts are opposed by Isaac's party throughout all of the game. She is the elder sister of Karst, who features in Golden Sun: The Lost Age as an antagonist in a similar vein.
