Human version of late Jonathan Brisby^^ Considering my "Mrs. Brisby and Bund of NIMH" AU, Jonathan Brisby would be introduced as a war/independence hero from warring time, one of the founders of the Bund for all humans that has became an "artificial vampires" under torturous experiments of NIMH (National Institute of Mystical Health), he himself is those kind, as they are dubbed as "IM-Humans" (rodents of NIMH in this AU).

There are still a lot of questions/mysteries regarding him, as he created the ruby Stone for his wife Elizabeth Brisby as only Nicodemus seem to know how; through alchemy. Formerly, Jonathan was meant to succeed Nicodemus to be the leader of IM-Humans, but his death made the seat of Nicodemus' successor vacant.
