Raven is a mysterious character in my webcomic that so far is named 'Wolfcomic'. She appeared one day before our hero when he was about to die in a snowstorm, and apparently saved his life. So far she has not made another appearance, and her intentions towards him remain unknown.
This is the scene where she appears in the snowstorm, transforming from a raven into a humanoid figure.
