Charlie stood in the training yard, sweat pouring down his face as he sparred with Ser Criston Cole. The knight had taken him on as a squire, teaching him the ways of combat and chivalry. Charlie was determined to make his family proud, especially his sister, Princess Rhaenyra Targaryen.

As he swung his sword, Charlie could feel the princess' eyes on him. She often watched him train, fascinated by the art of sword fighting. Being a princess, she was not allowed to train herself, but she loved to watch her brother and dream of one day being as skilled as him.

Rhaenyra had always been alone, never having any siblings to play with or confide in. But now, she finally had a brother, and not just any brother, but one who was training to be a knight. She was proud of him and wanted him to do well within their house and family.

Ser Criston was impressed by Charlie's progress. He could see the determination and drive in the young boy's eyes. 'Have you ever fought before, Charlie?' he asked, curious about his squire's experience.

Charlie paused, wiping the sweat from his brow. 'Yes, Ser. In medieval England, I fought to protect my village from invaders. It was a different time, a different life.'

The other knights who were watching were surprised. They had never heard of a squire with such experience. But Ser Criston nodded approvingly. 'Never forget, my fellow knights, that even the little guys can fight. Charlie here is proof of that.'

As the training session ended, Charlie walked towards his sister, still holding his sword. Rhaenyra smiled at him, her eyes sparkling with admiration. 'You were amazing, Charlie. One day, you will be the greatest knight in all the Seven Kingdoms.'

Charlie blushed at her words, feeling a sense of pride and responsibility wash over him. He knew he still had a lot to learn, but with the support of his sister and Ser Criston, he felt like he could conquer anything.

Together, the two siblings walked back to the castle, with Rhaenyra asking Charlie questions about his training and his plans for the future. For the first time in her life, she had a sibling to share her thoughts and dreams with.

As they reached the castle gates, Charlie turned to his sister. 'Thank you for watching me today, Rhaenyra. It means a lot to me.'

Rhaenyra smiled warmly at him. 'Of course, little brother. I will always be here to support you, no matter what.'

With that, they entered the castle, ready to face whatever challenges lay ahead. Charlie knew that with his sister by his side, he could accomplish anything. And Rhaenyra was grateful to finally have a sibling who she could call family. Together, they would make each other stronger and conquer the world.
