Chthon is a demonic deity who is one of a group of such beings known as "the Elder Gods."
Before Chthon first appeared in the Marvel Universe - in Marvel Chillers #1 - the Darkholders were referred to as "Satan worshipers." After Chthon was introduced, Darkholders were said to be worshipers of Chthon.
One manifestation of Chthon is "The Other." The Other is an Earthly aspect or elemental host of Chthon which is closely associated with the Darkhold. Marvel Chillers #1 is the first appearance of Chthon as "The Other."
