King of succubus

Why incubus became the most desirable species among the most powerful empresses and even by the primordial goddesses.

There's a famous legend on ALZANIA planet. Who says that every hundred thousand years, an incubus will be born, through a mystical ritual. He’ll possess mysterious powers that could allow any empress mage to reach divinity, any goddess to succeed supremacy!!....... But would the possessor of such power have the blessing of a peaceful life?!
