Question: is azor ahai the night king?
Answer: “Azor Ahai is the Night King and the Last Hero and Bran the builder.” This theory is the most interesting one to me[1] [2][3] [4] : Azor Ahai was the chosen one to fight against the darkness during the Long Night. He wields the Lightbringer, but only after sacrificing his own wife - Nissa Nissa - in the process.
