“S-someone! Come to my aid! All is lost if I fall!” —Roartz's battle quote
Roartz is the boss of Chapter 20A/Chapter 20B in Fire Emblem: The Binding Blade. Roartz is one of the two cowardly Etrurian nobles who turned against their country and joined Bern when King Mordred was captured. In Chapter 20A, he was put in charge of Murdock's Ilian headquarters, Castle Edessa, which formerly belonged to Zelot, leader of the Ilian mercenary knights, after Murdock decided to return to Bern. In Chapter 20B, he was defending a large manor on the outskirts of Bulgar against Roy and his army after Brunnya decided to return to Bern.
