Lunatishee (Scottish) - Wingless faeries that look like demons and which protect the Blackthorn Trees from invaders. They are covered in sharp poisonous thorns and they can also fire their thorns at enemies. They are mostly active during the night as their name implies. They absolutely hate humans and attack them on sight. They stand half as tall as a Gnome. (Fun Fact: Almost all D&D Devils and Demons look like random mythological creatures!)
The creature was humanoid, but it's body seemed to be made of woven wood. It's eyes were two glowing holes, and it's hair was a thick, elegant carpet of moss. It's hands were branches, leaves included, and it's feet were roots that twisted and dragged the thing along as smoothly as if it were walking.
Phooka, Brian Froud & Alan Lee - The Púca (Irish for goblin) is a creature of Celtic folklore, notably in Ireland, the West of Scotland, and Wales. It is one of the myriad fairy folk, and, like many fairy folk, is both respected and feared by those who believe in it.
