Aurelia Dreamglace (Aurelian (Human AU))

Aurelian is the crown prince of Abalasia (placeholder name), a country with a powerful military. He is the only child of the King Aulus and Queen Horatia, and he is very dear to both of them, despite however aloof they may act. 

Aurelian was close friends with Calliope when they were both preteens-ish. They met again when they were late teens/young adults and Aurelian began courting her.
