Shades are a specific type of demons that reside in the forest just outside of Shadetale. They are frequently referred simply as "Them". It is possible that the name of the town is derived from the Shades. Their elder claims that it was a human that murdered the man as opposed to a demon. However, this may not be true as when the Wolf was leaving the "Metal Demon", he was ambushed by Shades with knives.
The language that Shades speak is called 'Them' as well. The Shades come in many different shapes and sizes, some being pure evil while other being more mischievous.
