From Witcher to Lord of the Empire

"The one who came is the white flame dancing in front of the enemy's grave, the emperor of the Nilfgaard Empire——Emhyr va Enris."

Listening to the voice of the herald, Emperor Emhyr at the bottom of the steps looked at the man sitting on the throne—and his daughter sitting next to him—and couldn’t figure out how this short period of ten years , How did this guy change from a lost country dog to what he is today?
At this moment, the voice of the herald sounded again:

"Before you are the Lion King of Cintra, Heir of the Old Blood, Dragon Slayer, Sword of Dawn, Gryphon Rider of the Fairy of the Lake, Slayer of Monsters, Mentor of the Witcher Brotherhood, Warlock Lifetime Advisor of the Brotherhood, Archon of Novigrad, Academic Holy One of Oxburgh, Breaker of Slave Chains, Savior of Multi-Racial Equality, Breaker of Rime, Savior - Lane Lannister Ryan His Majesty Lun I!"
