Bucephalus - Almanac excerpt:
At night this mischievous fiend can be seen strolling around on the town's border in hope to snatch it's unsuspecting victims. Hiding it's evil appearance it normally shows itself in a black coat with white markings and bright green eyes. As soon as somebody approaches or enrages it flames burst out of it's body.

Named after the well-known steed Bucephalus this creature became something like a local legend in town. Many have fallen prey to the fiend while trying to catch the illusive coloured horse out in the plains.

A quick reference image for a creature appearing in a story I'm working on lately.
Also added a small excerpt of the full almanac entry for better understanding of it's behaviour.
