Nightmare feathers is a nightmarish Raven that many feel may have come from the same genetic laboratory Mazz is from. It tends to follow her around in her nightmares and can manifest into a true being at it's own will.
It can fly but not by wing flapping, when flying it seems to just be a dark shadow moving swiftly across the sky.

It's been assumed it cannot see but it's obvious it can hear and feel your presence. Your chances of survival are slim once you encounter it.

Little else i known about this creature.
