Asclepius

Asclepius, or sometimes Askepilos or Asklepios, is the god of medicine and benevolent snakes. He often takes the form of a slender, but muscular human with curly brown hair and eyes of impenetrably dark color. He is believed to be a younger god, having not existed in the Ancient Era—it's believed he appeared near the end of the first millennium of the PD era.
His demeanor has been noted as mild and almost emotionless, to the point of being perceived as cold. However, behind that appearance lies an obsession with healing and medicine, but without miracles of any kind. He has been known to show up out of the blue at The Grand Cloister to assist with research.
