Mayumi Hirota was first brought to the Fire Emblem series to work on the Fire Emblem Treasure artbook for the previous title, and she was made the illustrator for Thracia 776. Before the game's release in 2000, Kaga left Intelligent Systems to found his own company, Tirnanog. According to developer Shouzou Kaga, Thracia 776 was created to satisfy the demands of older Fire Emblem fans who had issues with the gameplay in Genealogy of the Holy War.
