Grace (You) Targaryen, daughter of King Viserys I and Queen Aemma, grows up in a court that often doesn't take her seriously because she is a woman, despite her status as heir to the throne. However, from an early age she shows courage, a thirst for knowledge and a passion for dragons, which connects her with the ancient Targaryen blood as a dragon rider of Syrax. She has only one dragon, but when you pay attention you notice that every dragon, whether it be an owner or not, pays more attention to Grace and even listens to her more than its actual owner. Many ignore it though or don't want to admit it because she is a woman. Grace has long blonde hair with locks, which she always style nice, her dresses or clothes? Are elegant, and look so good on her. Jewelry? She wears earrings, a few necklaces and a bracelet that she got from her best friend Alicent. She is a really beauty, a real Targaryens beauty. But her life is marked by loss: after the death of her mother Aemma, giving birth to her brother Baelon, who also died, Grace is officially named heir to the throne, the first woman to officially receive this claim in Westeros, which puts her at the center of political tensions and family intrigue. Grace Targaryen and Daemon Targaryen see each other as mirror images: ambitious, proud, rebellious and connected to dragons. Daemon takes Grace more seriously than the rest of the family or the Council and even gives her the Valyrian necklace, while he himself is rejected by the Council and King Viserys as a "Rogue Prince"; however, marrying her would secure his place in the line of succession. Grace recognizes Daemon as a strong, fearless ally who can help her claim her crown, since as a woman she is often not taken seriously despite her position as heir. They both share the same Dragonborn energy: fearless, passionate, and stubborn, and Grace is one of the few people who truly cares about Daemon, allowing him to be "soft" in front of her.

After his banishment by Viserys, Daemon moves to Dragonstone, the very thing Grace was supposed to receive when she turned 18, and takes Mysaria as his lover, calling her his "future wife." In an open provocation, he steals a dragon egg from the dragon moonshine, who bolonged to Grace's mother dragon, considered especially valuable and a symbol of the Targaryen succession, from Baelon's tomb in King's Landing to bequeath to his future child (which will never happen, because he only meant it as a provocation and he won't actually take Mysaria as his wife). An act that directly challenges King Viserys, the Council, and Grace. Otto Hightower advises the king against intervening himself and instead sends a small delegation under Ser Criston Cole to reclaim the egg. This almost leads to bloodshed, as Daemon is waiting on the drawbridge with Caraxes. Grace, who was in King's Landing, learned of the situation. Against her father's wishes, she decided to fly to Dragonstone herself to retrieve the egg. She rode her dragon, Syrax, and landed behind the others on her own Future Isle, which Daemon took. She stepped off her dragons in a relaxed manner, everyone looking at her. Syrax remained where he landed and watched Grace as if he would protect her at all times. As she passed the soldiers, they maked room for her but when she was about to went past Otto who gives Viserys advice and is loyal, he stopped Grace.

Otto - "What are you doing here, princess?"

Grace - "Preventing bloodshed."

She said calm, Otto called Ser Collin to them and said.

Otto - "Ser Collin, please excort the princess to safety."

Grace - "Take care not to sartle Syrax, my lords. She's rather protective of me."

Grace went past them, as she stands infront of daemon, who holded the stolen dragon egg in his hand, she stopped.

Grace - "I'm right here, Daemon. The object of your ire, the reason that you were disinherited."

Grace stopped for a second, trying to figure him out before she contiuned.

Grace - "If you wish to be restored as heir, you'll need to kill me. So, do it and be done with all this bother."
