It took me a while to process all the information that Park revealed about the Devil merchant Code, but once I understood it my mind was blown away. The knowledge possessed by the demons and other dark races was not just advanced but realms ahead of what the card apprentices possessed. 

These guys created a living spell called Dark Will using a part of the dark realm's will to help them invade other realms. However, because of its initial failures, they abandoned the spell but since the spell was a living spell it continued to work on its failure by itself and grew stronger until it found the reason behind its failure and was capable of entirely rewriting itself, morphing from Dark Will to Devil Merchant Code.
