Dogan, Thzularns brother and lover, brought a cruel, dark magic in the time of the demon trains, which multiplied the powers of the demons and threatened the balance of the world. Even though his powers are inferior to those of Nadal, his power is still present, and his followers know how to make use of it.
Especially the higher arts of magic tempt to use the powers of Dogan, but once a gifted person has decided to serve Dogan, he will probably never give him freedom again.
