Cerulean Masters

The Cerulean Masters were a group of powerful warrior mages who decided that the multiverse would be better managed under their direct leadership. To this end, they pooled their resources and crafted a biological automaton with the experiences and skill of those that came before implanted in them. They saw this race of warriors as the perfect army to conquer the multiverse.

Eventually the war turned against them, when the war spilled onto the mortal plane, the mortals fought back with surprising ferocity and cunning. This would lead them into direct conflict with the masters. Due to their own arrogance and confidence, they were defeated. As a result of their failure, the masters were chained in the space between realms, to never again be free to spread their wicked ways.
