While most priests come into the disipline of Exorcism through lineage or decades of training, Jordanus proved a natural. The Plague known as Snake's Fever is a consuming illness, causing erratic and violent behavior as a hostile demonic entity overtakes a human host and their body is cooked from the inside out by an unending fever. The Plagued are usually abandoned, with only the trained Exorcists able to handle them in their final days; They are a threat to themselves and others, and people have long since decided that anyone infected is at moral and spiritual fault for their own infection.
But when Jordanus' devout, loving, charitable mother came down with Snake's Fever, he knew it was not her fault. With no qualifications, only love and loyalty, he cared for her in her final three weeks. And when the Vatican finally bothered to send an Exorcist, the man was so impressed by Jordanus' endurance that he recruited him into the discipline. Now, Jordanus is the leading authority in the practice; Though, his size and hardened appearance often confirm people's incorrect assumptions about what goes into performing excorisms. And so when the Vatican decided to send an Exorcist to muzzle the heretical Salma Auerbach, W.W., for infecting herself with a Plague, they send Father Jordanus to handle her under the false assumption that he is an expert in domination and oppression or unholy minds.
Instead, the tired old man and his empathetic heart can't resist the hope that Salma may find some treatment or cure. He gives her his support, monitoring her progress to keep less supportive members of the Vatican from hindering her efforts.
