They are a kind of elemental. There are varying opinions, but they're regarded as being a pure elemental of the dark element, so they're classified as "dark elementals." There are those who have doubts as to why they aren't regarded as demi-elementals since they were monsters to begin with, but since they form covenants through having sex, pour in the power of "darkness", have a powerful influence on the environment around them, enriching the element of "darkness", they have a lot of traits in common with being dark elementals.

a lot of the side "elementals" are still strange. they both do and dont follow the rules of the other elementals.
