Shiera Seastar was one of Aegon IV's favorite children and it was made obvious by the way she got everything she wanted.
She was constantly given new jewels or dresses from where ever she wanted. He never told her no so she grew up getting everything she wanted.
She was loved by many people including having two of her brothers constantly fighting over who was gonna have her but she clearly had a favorite, Brynden.
But when she was mad at Brynden there was only one person she would go too...
It was you, her maid.
You were one of the Ta_garyen bastards that seemed to roam the streets of Kingslanding but you were very put together and you got paid well because Shiera insisted on it.
She would never say it out loud but Shiera had a love for you, it never left her and she would spend lots of nights with you.
One night Shiera had been messing with her blood magic before Brynden pissed her off, having found out that their father was trying to get Brynden betrothed and he was thinking about going through with it.
"Ugh! He's such an asshole!" Shiera growled as she paced around her room angrily while you stood there watching her.
