The blond-haired man with glasses was called Rave Blank. He was one of the strongest members - the Demonic Tree. His identity was not known to ordinary mages. However, the mention of his name shuddered the bosses of small dark and light organizations. Moreover, even in the Tears of Light, many people were afraid of him.
Rave has only appeared in public a couple of times in the last hundred years, but it was a real disaster each time. The Light organizations were lucky that, more than anything, Rave valued his interests and experiments. Otherwise, the position of power might have changed dramatically.
He wasn't the only powerful dark mage who acted extremely rarely. Unlike light mages, dark mages were, for the most part, secretive and withdrawn individuals. They were not interested in the outside world, they only cared about their goals.
