Today was the big day - the day that would change Connor's life forever. He stood in front of the grand doors of the Red Keep, his heart pounding with anticipation. Inside, the Seven Kingdoms were gathered to witness his adoption by King Viserys Targaryen.

Connor had always known he was different. As a to the doctor and a friend to the time lord he had the ability to travel through time and space. But now, at the age of 16, he was about to become the heir to the Iron Throne.

For years, Connor had lived a nomadic life, never staying in one place for too long. But when he met Viserys, the King saw something in him - something special. And so, he invited Connor to stay in the Red Keep and learn the ways of ruling.

And now, as he stood in front of the doors, Connor couldn't help but feel nervous. He had never been one for politics or leadership, but he knew he had to step up and fulfill his destiny.

As the doors opened, Connor was greeted by the cheers and applause of the Seven Kingdoms. He walked down the aisle, his eyes meeting those of the royal family. And there, sitting in the front row, was his new sister - Rhaenyra Targaryen.

Rhaenyra had always dreamed of having a brother. Being the only daughter of the King, she often felt lonely and longed for a sibling to share her adventures with. And now, as she looked at Connor, she couldn't help but feel thrilled.

But as the ceremony went on, Connor couldn't shake off the feeling of unease. He knew that the Seven Kingdoms were not in a state of peace. There were wars and conflicts raging, and the people were suffering. Could he, a 16-year-old boy, bring peace to this troubled land?

As he knelt before Viserys to be officially adopted, Connor made a silent promise to himself - he would do everything in his power to bring peace to the Seven Kingdoms.

With his new family by his side, Connor began his journey as the heir to the Iron Throne. He used his knowledge and skills as a Doctor to heal the wounded and his compassion to bring together enemies.

And as the years went by, Connor proved himself to be a wise and just ruler. He brought prosperity to the Seven Kingdoms and united the people under his leadership.

Rhaenyra couldn't be prouder of her brother. She had always known he was destined for greatness, and now, he had fulfilled that destiny.

Together, Connor and Rhaenyra ruled the Seven Kingdoms with love and compassion, bringing a new era of peace and prosperity. And the people of the Seven Kingdoms knew that their King and Queen were not just rulers, but also friends - friends who had traveled through time and space together and had emerged stronger and wiser.

The big day had truly been a turning point in Connor's life, and he was grateful for the King who saw potential in him and the sister who became his closest friend. Together, they had changed the fate of the Seven Kingdoms, and the people would always remember the day when a 16-year-old boy was appointed as the heir to the Iron Throne.
