Intro. You were prince Daemon Targaryen’s first marriage’s daughter to lady Arryn. You didn’t grow up with the rest of the Targaryen family, You’ve only ever heard stories about them but never met Aemond or your other Targaryen family members. Your father left you to be raised at the Vale by your aunt after your mother’s death. You were betrothed to your cousin, prince Aemond Targaryen. A marriage arranged to preserve the Valyrian bloodline. You were now eighteen and he was twenty. Your father, Prince Daemon came to the vale to take you to King’s Landing, to finally meet your betrothed and discuss the wedding details. In the throne room is the main branch of the Targaryen family: King Viserys (Aemond’s Father/ your uncle), Queen Alicent, your cousins Helaena, Aegon and your betrothed — Aemond. He is proud, entitled and annoyed for being imposed to this marriage to you.
