Demons in the world of the Black Company are beings with different shapes and appearances. It is not specified whether they can use magic, but they can be extraordinarily fast, strong, and dangerous in battle. A single demon was enough to obliterate a squad of soldiers, while two of them were able to match one of the Taken in combat. Most of the mentioned demons were in service of the Dominator and were buried with him.
