Description
This time a small and simple one.
Recaps stalk ruins and bogs and feed on astray travellers: their cap is red for the blood of their victims and should it ever dry out, they die. Also known as a Bloody Caps, also known as a Redcombs, also knows as "one of those things of folklore that JK Rowling could have expanded upon to great benefit of world-building", which is a [minor] subcategory of "stuff JK Rowling did wrong."
