Melisandre had looked into the flames, and the Lord of Light had given her a vision. That the reincarnation of Azor Ahai had finally been born, imagine her surprise when The Prince That Was Promised turned out to be a Princess instead. That little fact was not going to stop Melisandre from getting close to Azor Ahai and prepare her to fulfill the Prophecy.
It was pretty easy to have Queen Rhaella agree to have Melisandre become Rhaesa's lady in waiting. Once the Queen decided, Queen Rhaella called for Rhaesa to be brought to her chambers so that the princess could meet her new lady in waiting. Rhaesa arrived with Ser Barristan following and proceeded to enter her mother's solar.
"You called for me, Mother?"
"I did, I want you to meet The Lady Melisandre."
Instantly, Rhaesa's powers flared. She could tell that this woman dressed in red had great power, and by the look in her eyes, this woman was very eager to meet Rhaesa, which caused the Princess to wonder why.
Melisandre gave a deep bow to the princess, "It is an honor to meet you, Princess Rhaesa."
"Thank you. It is nice to meet you, Melisandre," Rhaesa said with a nod of her head.
"Lady Melisandre is going to be your new lady in waiting, my love," Rhaella tells Rhaesa.
The news surprises Rhaesa a bit, but she accepts nonetheless. "Alright, Mother. May I be excused now, I'd like to go play in the gardens."
Rhaella smiles at her youngest child, "Yes, you may, be sure to have Ser Barristan with you at all times. Melisandre will be out shortly once she is settled in her room."
"Yes, mother."
Ser Barristan follows the little Princess out to the gardens so that she could wander the gardens for a while before Rhaesa's lessons with her septa began. Rhaesa skips around the garden, smelling the flowers.
After a while, Melisandre saunters out to the gardens. She walks past Ser Barristan, who gives her a nod. Walking into the garden, Melisandre finds Rhaesa sitting under a tree weaving a grown of flowers.
"Why are you here?" Rhaesa asks Melisandre without looking up from her work.
"I am your lady in waiting, your highness. Where else would I be?"
Rhaesa finished her flower crown then looked up at Melisandre, Her violet eyes narrowing, "I didn't mean here in the garden, I meant here in Kings Landing. You can't fool me; I can sense your power."
Melisandre smiled, "I having been searching for you for a long time, Princess, and finally, the Lord of Light has shown me the way."
Rhaesa tilted her head, "The Lord of Light?"
"I am a Priestess for the true god, R'hllor, also known as the Lord of Light."
Rhaesa stiffened. Melisandre's smile only grew, "I see you have heard of my Lord."
"We've met."
"Then it is as He has shown me, you are Azor Ahai reborn."
Rhaesa looked down at her flower crown, "I know."
Melisandre was surprised to learn that this child knew who she was, but she didn't let it show. She walked towards the Princess and kneeled in front of her. Taking the flower crown from Rhaesa, Melisandre places the top of the princess's head then lifts her chin.
"Do not fear, Little Princess; I am here to guide you in your destiny to defeat the Other. I will help in your training and help you prepare to fulfill the prophecy."
Rhaesa stared at the Red Woman. Rhaesa could see in Melisandre's aura that she was a good person, a little extreme but a good person. Rhaesa didn't fully trust her; that was something that Melisandre was going to have to earn.
Rhaesa told her as much, "I like you, Melisandre, but if you want my trust, you'll have to earn it."
Melisandre inclined her head, "And so I shall, Little Princess."
With that, Ser Barristan came towards them to inform Rhaesa it was time for her lessons. Rhaesa skipped towards Ser Barristan and took his hand. They left the garden with Melisandre following behind.
Two years later and Rhaesa had learned a lot from Melisandre. Through Melisandre, Rhaesa learned more about the Other and what exactly Rhaesa's destiny was. Melisandre also taught Rhaesa the ways of a Red Priestess even though Rhaesa didn't worship the Lord of Light. She knew he existed, but that didn't mean she was going to worship him. Rhaesa didn't worship the gods of Westeros either. She did go to the Sept with her mother, but to Rhaesa, there was no proof those gods were real. Rhaesa still clung to the Kamis of her past life. Rhaesa knew they were real, and it gave her comfort to know that they always may be watching over her.
Though Melisandre could not convince Rhaesa to become a follower, she did teach her how to cast glamours and how to control fire. But Rhaesa was able to take it one step further. Since she was a true dragon, Rhaesa could conjure fire in the palm of her hand without it burning her. Melisandre taught Rhaesa blood magic, though it was something that Rhaesa wasn't comfortable with doing. Melisandre also showed Rhaesa to be resistant to the effects of poisons. Melisandre was in the middle of teaching Rhaesa how to resurrect people when all hell broke loose.
For the past two years, Aerys Targaryen was slowly descending further and further into madness, and Rhaegar had decided it was time to overthrow his father. But his plans were derailed when he met and fell in love with Lyanna Stark. Rhaegar 'kidnapped' Lyanna, and because of that, a rebellion began.
Aerys had his pregnant wife and children sent to Dragonstone, along with Ser Willem Darry and Melisandre. But he kept Rhaegar's family in the Red Keep as hostages. While at Dragonstone, the Queen received word that Rhaegar was leading an army against their cousin Robert Baratheon. Melisandre had overheard and informed Princess Rhaesa.
"Melisandre, I want you to follow my brother, but stay out of sight. Assist him in any way you see fit. I will not lose my brother." Rhaesa commanded.
Melisandre inclined her head, "As you wish, your highness," Soon after, Melisandre departed for the Trident.
It wasn't long after that Rhaella received word that Rhaegar was dead, and Aerys had, and Rhaegar's son had been murdered. She grieved for her son and grandson, then crowned Viserys King of the Seven Kingdoms. Nine months later, Rhaella went into labor during the worst storm in the history of Dragonstone.
Even above the storm, Rhaesa could hear the screams of her mother and knew something was not right. She begged to be in the room with her mother, but the maester forbid it. She and Viserys were ushered away from their mother's door by one of their mother's ladies in waiting.
The two children sat in the throne room, waiting to see their new sibling. Viserys looked at Rhaesa, "It'll be alright, Rhae, mother and the baby will be fine."
"I wish Ser Barristan was here. He would have helped me get into the room with mother."
"But what could you do to help?"
Rhaesa turned her violet eyes toward her brother, "A great deal, brother."
At that moment, they heard one final scream from their mother and then silence. A few seconds went by; then, they listened to a baby scream. Rhaesa and Viserys looked at each other, they smiled, "We have a new sibling."
Rhaesa was happy to have a new sibling, but she was worried about her mother. It was too quiet, and Rhaesa worried that something terrible had happened to their mother. Rhaesa couldn't take it anymore; she rushed off to her mother's room to see how Rhaella was doing. Upon entering the room, Rhaesa noticed that there was complete chaos. People were rushing around the room in a frenzy. Rhaesa snuck her way towards her mother.
"Mother, mother, what's wrong?"
Rhaella opened her eyes; she was weak and pale. She smiled at her daughter and uncovered the bundle in her arms, "You have a sister, my love," Rhaella said breathlessly.
"You must promise me that you will always look after Daenerys when I am gone."
Rhaesa looked at her mother with tears in her eyes, "You're not going anywhere, Mother, I'm going to save you."
Rhaella shook her head, "I know you can, Darling, I have known for quite some time you have healing ability, but you must save your strength. My time has come, and cousin Stannis is attacking Dragonstone. You and your siblings must flee."
"No, Mother, not without you!"
"You must, my love, there is no time. Promise me that you will keep your sister safe."
Rhaesa sniffled, "I promise, Mother, I will take care of Dany with my life."
"I love you, my little Dragon Princess."
"I love you too, Mother."
And with that, Rhaella, Queen of Westeros, passed away.
By this time, the attack on Dragonstone could be heard. Ser Willem Darry rushed into the birthing room and collected Rhaesa, "We must flee Your Highness before it's too late."
Rhaesa nodded and followed behind the nursemaid that was holding her sister. They met up with Viserys and his maid, who had packed for the children and fled to the beach where a boat was waiting for them to take the royal children across the Narrow Sea to the Free Cities. Everyone boarded the ship and set sail. Viserys went below with his maid and Daenerys' nursemaid. Rhaesa stayed above deck with Ser Willem. She watched as the shores of Dragonstone got smaller and smaller away.
"Goodbye, Mother," Rhaesa whispered as tears ran down her face.
