Fiend
The Mystics, also known as the Fiends in 600 AD and 1000 AD, are magical beings who originated in the Kingdom of Zeal.
Nature
Mystics are inherently magical beings, some even able to become magic users. Mystics are not all of the same form, there being many different species or sub-races such as Imps, Demons, and Naga. Even with these physiological differences, all Mystics are the same due to their common origin.
Some Mystics are immortal, while others live ordinary lifespans.
History
The Kingdom of Zeal
Mystics were "created" by powerful mages in Zeal, usually as part of their experiments. After their creation, they served the Enlightened Ones as servants, guards, and sometimes even jesters.
When Zeal fell, the Mystics scattered. After magic died in the hands of mankind, the Mystics - now the only beings in the world who could still use magic - saw no reason to serve them any longer. Over thousands of years, this difference grew into animosity, leading to war.
The War with the Mystics
In the Middle Ages, the fiends waged an all-out war against humanity, intending to wipe them from existence. They were led by the Fiendlord, and fought ruthlessly until the time that their lord could bring to bear the ultimate weapon, Lavos.
Medina
In the Present, the only remaining group of Mystics live in Medina Village on the East Continent, where they await the return of the Fiendlord. After Magus is defeated in the past, the timeline changes so that the villagers now pray for the return of Ozzie. After Ozzie's defeat in his fort, the timeline changes again so that the surviving Mystics are now allies of mankind.
