Azor Ahai was a legendary hero who lived approximately eight thousand years before Aegon's Landing. [Citation Needed] It is said that during the midst of The Long Night, Azor Ahai rose up and defeated the Others, wielding a sword of fire, called Lightbringer.
The Legend of Lightbringer
Darkness lay over the world and a hero, Azor Ahai, was chosen to fight against it. To fight the darkness, Azor Ahai needed to forge a hero's sword. He laboured for thirty days and thirty nights until it was done. However, when he went to temper it in water, the sword broke. He was not one to give up easily, so he started over.
The second time he took fifty days and fifty nights to make the sword, even better than the first. To temper it this time, he captured a lion and drove the sword into its heart, but once more the steel shattered. 
The third time, with a heavy heart, for he knew beforehand what he must do to finish the blade, he worked for a hundred days and nights until it was finished. This time, he called for his wife, Nissa Nissa, and asked her to bare her breast. He drove his sword into her living heart, her soul combining with the steel of the sword, creating Lightbringer.
Azor Ahai come again
Main article: Azor Ahai/Theories
According to prophecy, in ancient books of Asshai from over five thousand years ago, Azor Ahai is to be reborn again to challenge the Others. This will occur after a long summer when an evil, cold darkness descends upon the world. It is said that wielding Lightbringer once again, Azor Ahai will stand against the Others and if he fails, the world fails with him,
|“||There will come a day after a long summer when the stars bleed and the cold breath of darkness falls heavy on the world. In this dread hour a warrior shall draw from the fire a burning sword. And that sword shall be Lightbringer, the Red Sword of Heroes, and he who clasps it shall be Azor Ahai come again, and the darkness shall flee before him. ||”|
Some readers believe that Azor Ahai reborn is the same hero as the prince that was promised, while others believe that that is erroneous and that they come from two distinct prophecies. Azor Ahai and the prince that was promised have thus far never been mentioned in the same sentence although Melisandre of Asshai has mentioned the prince that was promised  and Azor Ahai interchangeably, however she tends to use the name Azor Ahai far more often.
|“||"A sign was promised." ||”|
|“||I pray for a glimpse of Azor Ahai, and R'hllor shows me only Snow.||”|
|“||"When the red star bleeds and the darkness gathers, Azor Ahai shall be born again amidst smoke and salt to wake dragons out of stone.||”|
