Species: Shadow Walker
Family: Living Shadow
Risk level: Medium
Weaknesses: Direct sunlight when without a host, otherwise positive thinking
Description: Shadow monster feasting on nightmares. Without a host it takes a form of mostly circular shadow. Unlike most shadow-likes it cannot move on walls or ceilings. When connected to someone it fuses with original shadow and takes over its form. If you happen to see a shadow not attached to anything it is highly advised to turn around and leave or if escape is impossible shine a bright light directly at it.
If it's already fused with someone it will start to emit dreadfull aura. After a while it will cause the host to experience extreme nightmares and unrestful nights. After that point the shadow walker will start to feast on it's victim and in turn grow rapidly. When it has consumed enough energy, it breaks apart into five smaller copies of itself. If not removed in time it could cause severe mental damage and in extreme cases, possible death due to lack of sleep.

When you see an animal with symptoms of possession you should put it down as fast as possible. Animals don't experience positive emotions as much as we do and there is no known instance of animal getting rid of parasiting shadow walker. Fortunately for humans it is easy to repel it if its victim experiences a lot of positive feedback from its surroundings, so in case of affliction, it is recommended to spend as much time with your family or loved ones as possible.
Personal notes: "Every living shadow is a pain to deal with, but shadow walkers are usually mild cases, because a shadow walker`s influence on living being is limited and easily negated. Unfortunatly the majority of their population hides in places that no humans reside, so their number is growing quickly. When we deal with more important threats we will send an expedition to limit their spread." Henry Blackeye, Member of Blood Hunt
