I've met the soul you call Lucifer, but what do you want from Him? All you have to do is call upon Him.
Be careful. He's the most beautiful thing you'll ever see. And that, my friend, has great power. No circle of salt will help you if He chooses to do something to you. You best not call upon Him without good Intent.
The fallen angels have most likely been called upon by powerful individuals in the world today i find it very interesting that Crowley was talking to a demonic spirit he named Lam he drew this spirit it looked like an alien grey ...Makes you wander
I know how to, I have before... No he isn't going to bring the apocalypse (this isn't the supernatural tv series)... He's the demon of pride; out of every entity I've summoned he's not the most agreeable. Personally I think Beelzebub makes better conversations.
I agree with everyone else. If you are new to summoning deamons, Lucifer should not be summoned. Try less powerful deamons first, and work your way up. I am genuinely interested in this, however, so message me with the results!
