In the past, there were three Grand Mages—even before Serah Crimson became one.
They were considered extremely powerful—elites in their own right. It was trite that they would be considered the strongest in the entire Eastern Kingdom.
Elrich Lendertwale—the Royal Court Mage
Mordecai Kaelid—the Great Sorcerer King
Reed Sterling—the Revolutionary Magic Scholar
These three led the golden age of the Eastern Kingdom, especially when it came to the advancement of Magic.
Elrich developed countless Magic artifacts and explored the functions of several Magic ores as well as monsters in order to determine the effects they had on one another.
Mordecai was regarded as the most powerful and diverse when it came to his Magic Ability. He was the battle axe of the Eastern Kingdom, and it was said that he singlehandedly defended the Eastern Kingdom from the invasion of unstoppable Monsters—making him a legend.
