Ok, I am feeling somewhat lazy for the moment, and nothing comes to find. So, I have decided to give you a special treat! This is from an earlier writing, where I researched some information on angels and demons, since they are something I am very interested in (I don't know why, don't ask lol). Since it is a lot of information, I shall split this into two entries. This will be the demons, and above this one will be the angels.
Demon comes from the Greek word daemon (δαίμων), which simply means spirit. In Judaism and Christianity, demon has come to mean an evil spirit. Demons have been blamed for a wide range of problems, from disasters to disease and devastation. Demons are the opponents of angels, and in some ways almost ironic, since the demons come from the ranks of angels. They are referred to as "fallen angels". Like angels, fallen angels come from all of the chiors. They are said to be very strong, and very evil, although usually they are defeated either by angels or by willpower, as in the case with exorcism. Demons were things to be feared and hated, which required God's intercession to defeat.
Demonology became a popular area of study in the Middle Ages; books called grimoires proliferated around this time, with ways to summon, subject, and otherwise use demons to the caster's advantage. Many people wrote grimoires, including kings and popes. Some were even attributed to King Solomon. These grimoires recorded many different demons with many different stories to them.
Many demon names are either taken from Jewish evil spirits or other deities; it seems that the Jews/Christians consciously or subconsciously demonized other deities, like Baal and Beelzebub, in order to show the superiority of YHWH/the Trinity over the other gods. An interesting way to integrate the deities of other cultures while simultaneously declaring the Trinune God as the one true God.
Since the demons are really fallen angels, they also correspond to the Angelic Choir. It would be impractical to give the demon's original location in the Angelic Choir since there is much dispute over their origins.
List of Demons:
Adramelech- He was a sun god worshipped in the city of Sepharvaim. The "melech" in is name means king, and the "adra" is fire, thus, "king of fire". Adramelech has been related to the Babylonian Anu and the Ammonite Moloch. He is given the appearance of a peacock or a mule.
Astaroth- Called the Prince of Hell, Astaroth has the appearance of a man with dragon wings, hands, and feet, while riding a wolf and holding a serpent in one hand. He is said to be able to teach science, math, and handicrafts, and also has the power to turn men invisible and answer any question asked of him.
Asmodeus- Also called Asmodai. He appears in the Book of Tobit as a demon attracted to Sarah, when he was defeated by Tobit and Raphael. His name comes from the Avestan language aēšma-daēva ("wrath" "demon"), but the Zoroastrian aēšma-daēva and the Jewish Asmodai are different entities.
Abbadon- A demon, or angel appearing in the Book of Revelation, who is the leader of a horde of locusts. Deriving from the Hebrew name "destruction", he is the guardian of the abyss and the angel of death.
Apollyon- The Greek for "Destroyer", he is the leader of the locusts of Revelation, and thus can be equated to be Abbadon. He is also similar to the Greek Apollo, although Apollyon is not influenced by Hellenic ideas.
Baal- a chief Semetic deity. He is one of the most popular deity to worship in Biblical times. The name Baal can also mean "Lord", such as Beelzebub (Lord of Zebub). In Semetic religions, many gods were referred to as Ba'al (Lord), and thus, later demonologists simply thought all these Ba'al's to be one and the same. His Semetic predecessor was usually in the shape of a bull or a man.
Belial- It is not sure what his name means, but most commonly translated as "without worth". Belial has been called a respectful demon. He is also a prince of Hell. Belial's name has been used to indicate the worthless in the Old Testament.
Beelzebub- A chief demon in hell. His name is said to arise from the Hebrew Ba'al Zebub, "Lord of Zebub" (or Lord of Things That Fly, thus "Lord of the Flies"), which is thought to be a corruption from Ba'al Zebul, "Lord of the High Place". His name is sometimes used interchangebly with Satan. He was worshipped in the Philistine city of Ekron.
Grigori- Greek for "The Watchers", a group of fallen angels who mated with mortal women and fathered the Nephilim, the giants in the times of Noah. They taught mankind secrets of civilization, like cosmetics and weaponry.
Nephilim- The children of the Grigori and mortal women. They were said to be wicked giants, and were the reason why God sent the flood. The Nephilim were likened to the indigenous peoples of Canaan.
Lucifuge- Latin for "he who flees the light" (lux fugio, "to flee light"), Lucifuge inflicts diseases and cause earthquakes. He is errornously equated with Mephistopheles. He has power over all the world's treasures.
Legion- The demon that was made from a conglomeration of other demons. This demon was named in the New Testament when Jesus drove him out from someone and promptly possessed a herd of pigs.
Rahab- A giant sea monster, he is also considered a demon. Like Leviathan, Rahab is a lord of the sea, and later on, became synonymous with Leviathan.
Satan- Chief demon in Hell, Satan is the usual leader of the demons and also associated with Lucifer. In Judaism, Satan's role in the Heavenly Court is that of an adversary, if you consider Heaven to be a court of law. He is the "tempter"; even his name, HaSatan, means "the adversary". Satan in the Hebrew sense is not inherently evil; in the Book of Job, he tests Job with many ills and devastation, but he can only do what God allows, which doesn't match up with our conception of a Satan that does evil to spite God and ignores His mandates. The jump from Judaism to Christianity made Satan into the villain that he is perceived as today. He is attributed to Beelzebub, Baal, Samael, Lucifer, and a host of other names.
Lilith- Said to be the first wife of Adam, before Eve. The first form of Lilith was a class of Sumerian storm demon called lilitu. The only mention of Lilith in the Bible occurs in Isaiah, where it is said that Lilith rested in the desert. Lilith is also said to be the wife of Samael (who is sometimes synonymous with Satan). She is a tempter of men, and brings them to their ruin, much like a succubus.
Baphomet- a demon with a goat head. His name is most likely a French corruption of Mahomet (Muhammad). Some people have accused the Knights Templar of worshipping Baphomet.
Mephistopheles- A minor demon, he was the center of the story of Faust and the demonic pact. Faust made a deal with Mephistopheles in order to gain occult knowledge. Mephistopheles becomes more popular as time went on, becoming the main character in the Faust legend. He is sometimes equated to Satan.
Belphegor- Originally the god of licentiousness of the Moabites, Baal-Peor, he became a demon associated with laziness. He has the power of discovery and helps people with inventions. He appears in the shape of a young woman.
