I thought it would be interesting to inflict one of our covenantâ€™s grogs with St. Anthonyâ€™s Fire (City & Guild, pg. 27), but I am a little uncertain how to handle some aspects of it.
We are told the illness is caused by a â€œminor demon in the victimâ€™s intestines.â€ Cool. Our magi are both healers of one sort or another, and they have battle demons and diabolists in the past, so this sounds like good fun.
So, if a demon takes up residence in a grog is that physically or spiritually? Most importantly, what would happen when the grog attempted to cross the covenantâ€™s Aegis of the Hearth? (It can certainly protect the against a creature with Infernal Might 10.) Would the grog himself be prevented from entering? Would the act of crossing the [i]Aegis[i] drive the demon out of his body?
Secondly, it shouldnâ€™t be too hard for the magi to identify that a demon of some sort is causing the illness. Even though Hermetic magic cannot identify the demonâ€™s presence the characters have sufficient skill in mundane healing, Intellego Corpus, and infernal lore (shhâ€¦ donâ€™t tell anyone) to rule out other sources. Would a Rego Vim ward against demons (targeted on the inflicted person) drive out any demons even if they have not been independently identified?
Finally, C&G says that the wounds inflicted by the disease demon are magical. Should I take that to mean that the Medicine skill would be insufficient to treat it? Are there diseases that are supernatural and thus beyond mortal ken? Or can it still be treated with the standard disease rules?
Thoughts are appreciated.
