Nope, you have it all wrong, Lucifer is a male entity, a God, his sister is Hecate (Pronounced Hek-a-Tay). You may have Lucifer mixed up with his sister. Hecate is a very powerful Goddess, she is the Goddess of the waning moon, the Crone Goddess.
I was just reading about a spell that invokes her name and said it out loud, my sleeping Chihuahua began barking and whining in his sleep the moment I invoked her name. If you ever want a powerful spell to bring you protection, and if you are a Wiccan or other such pagan, invoke Hecate and you have nothing to fear from anyone.
Lucifer is the light bringer. It is also another name for the planet Venus.
