Vagran-Demons are a species from my high/dark fantasy world. While they resemble wolves superficially, they are in no way related to them, but actual demons, and their behaviour is much different. Only vagrants (travelling minstrels, jugglers, thieves, vagabonds) are able to see these lion-sized beings, for everyone else they are invisible.
It's hard to draw with only a touchpad, so excuse the sloppy look of this.
