Azulon

Fire Lord Azulon was the ruler of the Fire Nation starting from 20 ASC. He was the son of Fire Lord Sozin and was Fire Lord before Iroh. He was husband to Ilah, father to Iroh and Ozai, and grandfather to Prince Lu Ten. He was also responsible for the near destruction of the Southern Water Tribe, which was nearly annihilated under his orders. Although seen as uncaring and cruel, even toward his own people, he is remembered as one of the Fire Nation's strongest and most effective leaders.
