Lucifer is just another name for Satan. He is the head connection that Keeps hell in tact And commands every lesser,prince, and any other demonic Creature that lives in the domains of Hell. He is said to have another copy that rules over the Netherealm. But the two appearances strangely fool even the strongest perceptive mortals and immortals. With a massive army it is little he has the privelage to do outside his domain in the spirit realm. Lucifer waits for the right time to strike fear and death to the mortal realm which he calls "The Light which has taken whats rightfully his".
