Does anyone know anything about the Demon Crael?
Serious question.

There is no demon Crael. Is it from a game or movie or something?

Crael, to the best of my knowledge, is not a legitimate demon in the Judeo-Christian theology.

During the Christian Dark Ages the Church demonized everything that went in opposition to their own twisted branch of moral relativism. Simple offenses: like epilepsy, gluttony, restlessness, sickness, and more were all branded with "demons" like Glasya-Labolas, Barbos, Belphegor, etc. These demons, however, were simply made up out of thin air in order to keep the public subjugated to the will of the Church.

Other demons supported by Christian theological texts are actually just old pagan gods and deities: Beelzebub is really Ba'al from the Levant; Astaroth is really Ishtar from Babylon; Amon is really Amun from Egypt; Adramelech is actually an Assyrian sun-god by the same name; etc. The Church was ruthless in it's desire to bring the entire population of all the known lands under Christian rule. When pagans refused to accept, their beliefs were simply turned into the works of Satan.

If Crael were to be anything, it would most likely be an angel, not a demon. The suffix "el" at the end of words of a Hebrew nature often signifies that it is "of God". Michael, originally Mikha'el, means "who is" (Mikha) "like God" (el). So, if "Cra" is a Hebrew term, then you might be able to make some more sense of this "demonic" entity. I do know that the "KHR" combination in Hebrew often has something to do with "necks". Perhaps Crael may be the neck of God? Don't know for sure.

Good luck on your search.
