Shades are spirits possessing a living mortal, dominating the mind. Slowly consuming the soul over time through the continued use of their power. Such creatures are strong, any spirit would have arcane power far beyond any mortal wielder of magic. But a possessed vessel is limited, using too much of their power too quickly and too often will slowly decay the host. Such a shade can be ritually exorcised and the spirit banished. But this must be done quickly, before the soul of the vessel is consumed and destroyed. A shade can be created through many circumstances, an enchanter binding a spirit to themselves, or even a summoning gone wrong. The possessing spirit could be anything, celestial, elemental, ancestral, infernal or abyssal. Not all angels are good, not all demons are evil, a spirit is not always what they seem. While the creation of a shade is a rare occurrence, they are always a terror upon the land when they appear. With silvered steel being the only known metal able to physically damage them.
