Glenn is a middle-aged man, with neat grey hair and a scar just above his left eye. He wears a white wedding suit. Glenn is a brilliant merchant and an expert in close combat, as well as a capable biologist who can engineer his own virus strains. He greatly mourns the loss of his wife Sarah, and as a result has deluded himself with a fantasy of redoing his wedding day by any means necessary. He can be kind, but will take cruel and even inhuman measures if it will help him to achieve his goals.
