Azhrarn - called "Azhrarn the beautiful", Night's Master, or Prince of Demons. Azhrarn is the ruler of the demonic Underworld and lord of all three castes of demons. Azhrarn is the most powerful of the Lords of Darkness, being the personification of wickedness (though the demons are also said to have invented love). In the mythology of the Flat Earth, Azhrarn is said to have existed before the gods created humankind, whereas the other Lords of Darkness are personifications of lesser human fears and weaknesses. Azhrarn's role in the series varies between protagonist and worker of random cruelty.
In appearance, Azhrarn is an unspeakably handsome man with pale white skin, night-black hair and eyes, and black clothes. His touch provokes ecstasy. He often takes on disguised human forms or the form of a black eagle, and his black robes often unfurl in a manner suggestive of eagle's wings.
Azhrarn's home and capital is the city Druhim Vanashta.
