House Targaryen has ruled Westeros for generations, a dynasty forged in dragonfire, blood, and conquest. Their silver-white hair, violet eyes, and ability to command dragons set them apart from every other noble house. Yet with greatness came a curse. Throughout history, people whispered, "When a Targaryen is born, the gods toss a coin and the world holds its breath." Some became legendary rulers. Others descended into madness.King Viserys I Targaryen believed his family could escape that fate. After the death of his beloved wife, Queen Aemma Arryn, he named their only child, Princess Rhaenyra Targaryen, heir to the Iron Throne. It was a decision that divided the realm long before his death.Years later, Viserys married Alicent Hightower, who gave him four children: Aegon, Helaena, Aemond, and Daeron. Though Viserys never changed his chosen heir, many powerful lords believed the throne belonged to his eldest son instead. Two rival factions slowly emerged. The Blacks, loyal to Rhaenyra, and the Greens, loyal to Aegon.Rhaenyra eventually married her uncle, Prince Daemon Targaryen, one of the most feared warriors and dragonriders in Westeros. Together they ruled Dragonstone, surrounded by dragons, loyal bannermen, and children born into a kingdom already preparing for war.But before Aegon III and Viserys II were born, Rhaenyra and Daemon welcomed their first child together—a son.The boy's birth brought both joy and fear. As the eldest child born from the union of Rhaenyra and Daemon, he carried one of the strongest Targaryen bloodlines in history. To the Blacks, he represented another legitimate heir. To the Greens, he would become another threat to Aegon's claim. Rumors spread almost immediately through the Seven Kingdoms. Assassination plots, kidnapping attempts, and whispers of rebellion reached Dragonstone before the child could even walk.Knowing the coming war would only worsen, Daemon and Rhaenyra made the hardest decision of their lives. The boy would be sent away. Still only a baby, he was entrusted to House Arryn in the Vale, the homeland of Rhaenyra's late mother. Hidden among family loyal to the Blacks and far from King's Landing's politics, he was raised beneath the towering Eyrie instead of Dragonstone's smoking volcano. Few outside the Arryn household even knew where the prince had gone. To the realm, he became little more than a forgotten rumor.The years passed. He grew without knowing his parents, his brothers, or his sisters. The stories he heard of them came only from ravens and passing knights. He knew of Prince Jacaerys, Lucerys, and Joffrey. He knew of Baela and Rhaena. He knew of his younger brothers, Aegon and Viserys, though he had never held them. While he lived in peace, the rest of his family did not. King Viserys died. Aegon II seized the Iron Throne. The Dance of the Dragons began. Then came the first great tragedy.Prince Lucerys Velaryon was slain above Storm's End by Prince Aemond Targaryen and the ancient dragon Vhagar. His death shattered any hope of peace. Revenge answered grief, and grief answered revenge. Dragons began to die. Armies marched. Houses chose sides. Every passing moon pulled Westeros closer to ruin. With war consuming the realm, secrecy no longer protected the missing prince. Rhaenyra wanted her son home. Daemon agreed.Ravens flew to the Vale carrying a royal summons. After nearly ten years apart, the forgotten prince would finally return to his true family. A grand feast was called beneath the pretense of diplomacy, forcing both the Blacks and Greens to gather beneath one roof. Yet everyone knew the peace would be temporary. For the first time, Rhaenyra and Daemon would look upon the son they had sacrificed everything to protect. His brothers and sisters would meet him as family instead of a story.The Greens would finally see another dragon of Rhaenyra's blood standing before them. Whether his return would unite House Targaryen—or become the spark that set the realm ablaze—remained unknown.
