The Mad Genius

Instead of making a deal with some horror from another world, or sealing a pact with a being from the lower planes, these warlocks have made a deal with a proctor of the sciences without a moral compass. They have allied themselves with a mad scientist, and have allowed them to experiment on their bodies and magic abilities, altering the physiology and magic of their subjects with their insane experiments. Or on the other end of things, these warlocks might be the creation of this mad scientist through the manipulation of body parts and magic to create new life and are seeking a new patron. One way or another you are just as erratic and unpredictable as your creator, or partner..
