Since the path of the mc is visionaty i guess that you will make the mc take a roll like guiding events and people to the way he want and pretending to be just a regular member of the organization he build, after all this way is the best for acting no to direct, a dog sleepless will be a good idea too cause animal are more trustest that humans at the beggining and i felt it more in line with a dog that path, a assassin also is a good idea and as far as i know animal will became human woman when drinking witch potion, cause witch not only represent a female creature but also a human female.
