Grandia is a set in a fantasy world where societies thrive in an era of increasing technological developments following the collapse of the ancient Angelou civilization centuries before. General Baal, leader of the militaristic Garlyle Forces, along with his son Colonel Mullen and Mullen’s love interest Lieutenant Leen, make their way to an archaeological site where treasures of the ancient people are believed to be resting.

Grandia III takes the adventure to the skies, putting you in the role of Yuki, a young man with dreams of flying his own plane. He soon comes into contact with a young girl named Alfina, a Communicator who can speak with the Guardians–giant beastlike gods who protect the citizens. As the world faces the greatest danger it has ever known, can a would-be pilot and an inexperienced Communicator save them all?
