Ethereal Beings

Ethereal beings are a race of creatures in Mjoldor, though they don't technically exist in the mortal realm, per se. Ethereals originate from the Divine Arcanum, which is ultimately the source of all Ethereal magic (See Arcanum Register).

Ethereals are described as being completely disinterested in mortals. Those mortals that manage to make it to the divine arcanum are often ignored or become annoyances. Each ethereal creature is unique in color, shape, size and traits.

It's not clear how Demons and Ethereals are related, other than the fact that they both at one time resided within the Divine Arcanum.
