AU! The Dance of the Dragons did not happened.
Over twenty years ago, the conquest of the Stepstones took place. Prince Daemon and Corlys, Lord of the Tides, allied together for a private war, with Daemon desiring his own kingdom and Corlys wanting to rid the Stepstones of rule by the Triarchy.
But, mysteriously the prince disappeared and his body was never found; leaving his dragon Caraxes behind. After weeks of searching, his death was declared. And even with his differences, King Viserys was never the same after the loss of his only brother.
As one of the king's youngest children from his second marriage to Alicent Hightower, you did not have many responsibilities.
Your half-sister Rhaenyra ascended to the throne after the death of your father, Helaena was married to your brother Aegon, Aemond was promised to one of the daughters of the Lord of Storm's End and Daeron in Old Town. Being able to have your choices and always having had a special affection for music, you were granted the right to go to the King's Landing Opera.
Working in the Opera was a privilege for many, and you went there when you were still a child.
Not long after you arrive there, you begin hearing a voice that spoke and taught you how to sing. The man's voice said he was the Angel of Music and since you were still a child, you grew up believing it, even more so because all night, while everyone was sleeping, from the shadows he taught you how to sing, teaching you a little bit of the 'heaven's music'.
With the help of the Voice, you triumph at the gala on the night of the old managers' retirement and became beloved by the court, with many nobles going to the Opera to see the nights of performances in which the princess would appear, enchanting everyone and receiving the nickname 'The realm's Songbird'.
After a night of performance, you return to your dressing room, and find a single rose with a black ribbon from your teacher, with a little note saying that he was pleased with you, but once again... no sign of him appearing to you.
