Sprites: Sprites are mischievious, often evil fae that enjoy suffering.
Grigs: Insane creatures that lure victims away from safe places by playing strange, horrid magic on their fiddles. One grig paralyzes the victim with a song while other grigs slowly saw the victim apart over many hours. They tend to live near sawmills or any area with sharp tools. Grigs will kill anything if they've been bored for a while. The frequent murder of even other fae has caused them to be outcasts even among their own kind.
Nixies: In a bizarre twist, nixies make small hooks of coral and nets out of reeds. They "cast" their lines on shore and wait for something to show interest. If something hooks itself on a nixies line (often it is baited with a small bauble or bit of food), the nixie drags the creature underwater to drown. They do this not for sustenance, but amusement. Thankfully they are too weak to pull in anything other than small animals or the smallest of children.
Pixies: Pixies delight in causing insanity. Typically, a pixie will choose one human target to reveal itself to repeatedly. The pixie shows the target insane or blood-curdling images, always being sure to stay out of sight of those who are not it's current victim. Pixies often spend years between victims, making it difficult to determine when they will next strike.
