A magical variety of raven, Nachtkrapp are as dangerous, if not more so, than their Nordic cousins, Valravns. Originally found in Germany they have now spread throughout Europe and have been introduced to - and indeed are common in - North America, often competing with domesticated Valravns for territory. Pale in colour, Nachtkrapp happily travel alone or in groups, but are known to mob children in incorrectly warded gardens - at present areas known to be inhabited by Nachtkrapp must be correctly bespelled to protect all children - magical or muggle - within their areas by ICW mandate.
Like Grims Nachtkrapp are considered omens of death, however, where the existence of Grims is still hotly debated by those who do and do not believe in some of the more imprecise Divinatory arts, Nachtkrapp are known to exist, and their ability to induce states of shock in those who look into their eyes is well known, attested to and recorded. While not immediately deadly, the body parts of Nachtkrapp are known to have severe degrading effects on mental wellness unless properly spelled, and as such the body parts of all Nachtkrapp require special permits in order to trade in - permits also kept by those few who have successfully domesticated Nachtkrapp and trained them to, instead of inducing shock via eye-contact, instead induce a soothing almost meditative trance.
Nachtkrapp feed largely on carrion and, when they successfully kill a child, they will feast on the corpse for as long as possible - carcasses of Nachtkrapp prey are picked clean with startling rapidity. Domesticated Nachtkrapp are usually fed mice and frogs, though rabbit meat is often used in training, and they are known to much enjoy pufferfish eyes, often depleting potions stores. The feathers of Nachtkrapp can be used as wandcores but due to the difficulty in finding and obtaining them, the ease of finding the equally powerful feathers of Valravn, and the fact that Nachtkrapp body parts are generally not traded this is very uncommon. Experimental wandmaker Pastor Edmund Bream has been known to use Nachtkrapp feathers before, and notes that owners of such wands are often exceedingly morbid.
