Sothis takes over Byleth's body and mind, who is the son of Jeralt, a mercenary captain of Jeralt's Mercenaries. Byleth traveled across Fódlan with Jeralt and his company for whatever job is needed. However, Byleth has the voice of a girl in his head, named Sothis. Sothis has come to take over Byleth's mind to keep her vessel away from anger. Sothis's consciousness has completely taken over his mind, so she disguises her identity as Byleth's.
