In the A Song of Ice and Fire novels, Lightbringer is a sword of legend, forged and wielded by Azor Ahai, chosen by the Lord of Light to fight the darkness. He wielded the blade during the Battle for the Dawn, where he led the Night's Watch and the Children of the Forest and defeated the Others and ended The Long Night. The sword was said to glow and radiate heat, burning whoever touches it.
