Though the term “Unseelie court” is Scottish, the tales of these faeries come from all countries. These are the most dangerous faeries, those that think nothing of causing a mortal pain for their own amusement. They use their illusions to confuse humans and lead them into danger.
Members of the Unseelie Court tend to be mischievous and out for their own good.
