Random plot hook from Time Team:
Digging up Sewardsley Priory, looking into accusations of various improprieties during the Wars of the Roses, which sound like the charges levelled at the Templars when they were taken out. There it was essentially an excuse to seize their goods, but here there was another suggestion:
Rich patrons had nuns praying for their souls. Discredit the nuns, discredit the patrons.
There’s got to be something in that, maybe for WFRP or Pendragon or Dark Ages WOD...
