A subspecies of Demon's from the webcomic Slightly Damned.

Demons come in a large variety of shapes and forms, more so than any other sentient species; they all take after real-life animals as well as mythical creatures. Most common features include long claws, horns and sharp fangs. Horns are a matter of pride for Demons that have them, and are considered a sign of beauty and strength. They may have fur, scales or feathers, the colors of which often tie in with their element, and often sport patterns such as spots or stripes.

Wind Demons are the second tallest of the four. They tend to take after a variety of airborne creatures, but most often they take after mythical creatures such as Wyverns or gargoyles. They are often green in color. All Wind Demons have wings of some kind that allow them to fly without the aid of Magic.
