Belial is by far one of the most popular demons in Occult Lore.
I say this because I have been on countless forums and group pages, and I have read several books in which they often mention.
We all take the occult texts as gospel and assume that what we read is all there is regarding Belial.
When looking through the occult literature one finds rituals to and descriptions of Belial, but there is little to no tangible history.
He is second only to Satan and in some circles, he is Satan himself.
