Samael

Samael, otherwise known as Sammael, was among the original and most powerful of Greater Demons, particularly a fallen angel of the highest order, along with Lucifer and Abbadon. He was the former lover of Lilith when she was still human.

History:
Samael was on of Gods highest ranking Archangels in Heaven. However, for an unknown crime, Samael was cast down onto earth, where he became the worlds very first Demon. Soon after this, Lucifer staged his rebellion against their Creator. However, when Lucifer was cast down with his loyal servants, Lucifer took over a small dimension he dubbed Hell.

Not wanting anything to do between the war of Heaven and Hell, Samael hid in the Garden of Eden with the first humans. There, he fell in love with Lilith, Adam's first wife. He watched as she was exiled to die on the world beyond because of her stubborness and defiance against her husband and comforted her, taking her in...and from their affair, the first Demons were born.

However, Lilith left Samael, seeking to join Lucifer's efforts against Humanity, and Samael was branded a traitor for not joining them.
