There are entities attached to this planet that seem so difficult to explain that we have developed a great deal of different names and characteristics to be attributed to them.
The most popular name is Archons.
Why the Draco studies, mimics, as well as uses them, should be obvious.
Others do as well, as mentioned. Several magical practices and disciplines utilize Archons and call them by other names. Another side effect of the abusive use of Archons and their general actions is the creation of demons.
