Mythos one

An example of my Mythos!

Race: Demons--- A short lesson.

They have been possessed by a creature that still causes scientists to go insane. And that's no coincidence.

They seem to produce a signal that screws up parts of the brain. Blindness,deafness,madness,these are all things that demons cause. Oddly enough,these creatures are called demons,yet they aren't the demons. They simply share the powers.
Also,people possessed by demons are basically dependent on demons,mainly because their body cannot take the shock of being "Disconnected" from the demon.
