The Book of Enoch is the source of the fallen angels rebelling and fighting against the angels of God story, and the source of the modern Luciferian Legend. The book of Enoch is non canonical in either Hebrew or Christian literature is apocryphal, but was cited in the book of Hebrews and in the Epistle of St. Jude so it was known to early Christian communities.
Summary: The name of the leader of the fallen angles is Samyaza, later changed to Samael, (Not Lucifer). Another rebellious Angel Azazel taught warcraft, weaponry, war, and sorcery to humans. The reason for their rebellion was to fornicate with hot earth women. They had babies called the Nephilim who were Giants. God destroyed them and cast them into a lake of fire and pit of darkness, and killed all of their offspring in the Noachian flood.
