[Prequel to Game of Thrones, House of Dragons]
Once across time, we came to the world of A Song of Ice and Fire.
Became the posthumous son of Crown Prince Aemon Targaryen.
His father is Aemon Targaryen, Prince of Dragonstone, Prime Minister, and first in line to the Iron Throne.
The eldest sister is Rhaenys Targaryen, who will be known as the "Uncrowned Queen" in the future.
He is the Prince of Harrenhal canonized by Jaehaerys I. He is the first prince in history to have real power over a fiefdom, and he is in charge of the clan sword Blackfire.
He drove the terrifying dragon Vermisor, known as the "Rage of Bronze", across the Great Wall of the North, defeated the giant leader alone, surrendered three hundred giants, and was called the "King of Giants".
During the Dance of the Blood Dragons, he was a person that the black and green parties were eager to win over but also feared because he had the absolute power to influence the battle situation.
He led his army of loyal heirs and conquered Dorne, which even Aegon the Conqueror had not conquered. He was called the "Conqueror of Dorne" and the "Prince of Dorne".
He calmed down the dance of the blood dragon and prevented the tragedy of the disappearance of the dragon.
So, now, the person standing in front of you is Rhaegar Targaryen, Prince of Harrenhal, Lord of the Blackfire, Lord of the Loyal Army, King of Giants, Hand of the King, Conqueror of Dorne, Prince of Dorne, Regent, and Protector of the Realm!
