This is a quick pic I did of a creature from the Etherealm, called a Windbane. Got the inspiration to do this after, through massive hallucinations or something else, I saw this outside my window on a fullmoon night. :/ Scared the hell outta me. The reason for this is that picture this, but with the tail mist being 20 feet long, with the head approx. the size of a large dog.

Windbanes, or Hellfog, are creatures of the wind element. When hiding in fog, they're completely invisible, but they can be seen under certain conditions, such as under the effect of moon magic. Being non-physical except for their teeth, claws, and horns, if they see you, you're screwed, to put it bluntly. Also part darkling, any evidence of their presence (shadow, cry, or seeing any part of them) is enough to spell you with fear. In other words, they suck.
