Franz is a playable character in Fire Emblem: The Sacred Stones. He is an earnest, sincere and determined young cavalier from Renais. He is the younger brother of Forde, and seeks to emulate his father, a great knight who died in Renais' service. His mother died of poor health, but according to Forde, Franz was too young to remember. He greatly admires Seth and can develop a fraternal bond with Natasha. He is also able to fall in love with Amelia. He enjoys fishing.
His loyalty to Eirika and Ephraim is surpassed only by that of Seth, and he strives to live up to his brother Forde's example.
