The Adlet are blood-sucking creatures based in Inuit mythology. They are also known as Erqigdlit to the peoples of Greenland and Baffin Island. Werewolf-like in appearance, it is said they are the result of a union between an Inuit woman and a giant dog.
The woman gave birth to ten fur-covered puppy-kids. Terrified, she set five of them adrift in the sea. According to the myth, these five managed to cross the Arctic and Atlantic and spawned the European races.
A theory proposed by the team of American Monsters is that, due to the questionable story of a woman having a child with a giant dog, it is more logical that the Inuit woman had relations with a Werewolf, or with a creature of Native American mythology, a Wendigo. The latter may explain the Adlets' taste for human flesh, although this could just be due to their carnivorous nature.
