The name "King in Crimson" is a loose synonym for Beelzebub, a derivation of the hebrew word "Ba'al-z'bub" meaning "Lord of the flies". In any case, it is referring to Satan, but not necessarily saying that Satan is bad, stay away from him. It's more likely saying Satan is all powerful, but evil nonetheless. The "Sons and daughters" part, I'm not quite sure of. And that's my analysis of this song.
