The Wraith World

All things in Midgard fall into the realm of either the Seen or the Unseen. The Unseen are objects and creatures of the spirit world that belong to "magic". The Unseen world is neither good nor evil and contains both dark and bright spiritual beings. As the name suggests, the wraith-world is the world where wraiths and other undead spirits exist. The wraith-world is a mysterious alternative aspect of reality that belongs to the realm of the Unseen. Some of the most obvious examples of Unseen creatures were the Death Eaters, which were invisible and formless.
