Goodman Games

I'm playing in a Hubris game starting tomorrow. I didn't want to pick up the book yet as to remain un-corrupted of knowledge. Based on the lore, can someone give me the summary of what a Pus Diviner is. Is it as horrifying as I imagine it is? (horror is not bad...).

No additional setting lore, just the usual meaning of pus diviner. Apply the old-school paradigm: take the random thing you've been given and run with it.
