Game of Thrones: From Emperor of Valyria to God

Timonce Bellerys, the last male descendant of the Bellerys family, a prominent dragonlord family of the Valyrian Freehold, who unexpectedly escaped the Doomsday catastrophe, was tragically sacrificed to R'hllor, Lord of Light, during the city-state's liquidation following the fall of the Valyrian Freehold. However, this blessing in disguise activated the Apotheosis System. From then on, his quest was unstoppable. He not only recovered the dragons and rebuilt the Valyrian Empire, but also solved the mystery of Valyria's fall and avenged his own genocide. He gradually became a living legend, an immortal myth, and ultimately, an eternal god. (If you're not satisfied with the Game of Thrones books, I've taken this one on myself. Please bear with me if there are any inaccuracies.)
