Redcap

Redcaps are the most evil fey you're ever likely to meet. They are mass-murdering psychotic killers who live on other creatures' pain. A redcap stands 3 to 4 feet tall, weighs about 50 pounds, and looks like a tough old man with protruding teeth. On their heads redcaps wear bright red hats - kept fresh and moistly colored by dipping in their victims' blood - and on their feet they wear boots of iron. Redcaps prefer to roost in old abandoned keeps and towers, preferably ones left vacant by some horrific tragedy. These fey absorb some of the essence of every creature they kill. Thanks to this ability, a redcap that manages to live a long life can amass tremendous strength and near invulnerability. When a redcap dies, it vanishes from the world, leaving only a single tooth behind.
