Crystal Sorcery is a form of magic in the dark souls series of games, it was developed by the dragon Seath the scaleless through a series of tragic experiments and was eventually adopted by humans. These humans were eventually driven mad and hollowed. Crystal Sorcery has always had a history of both being driven by the users intellect and being linked to a curse known as hollowing whose symptoms have always involved madness. For these reasons, I feel that a crystal sage perfectly fits the theme of mad science.
Already have a decent start on the guy, just about 2 days in and in the process of texturing him now.
