Convent of Corruption

An erotic horror scenario for old school roleplaying games. 

Content warnings: sex, violence, sacrilege

The Mother Superior of the Our Lady of Sorrow Convent is secretly in league with a lust demon. As time passes, the corruption spreads and the demon grows in power as the nuns give into their sexual desires. Who can the PCs trust? How can they banish the demon? Will they resist the lure of carnal pleasure or use it for their own ends?

The Demon’s sway over the convent increases with time. This is measured by the Corruption Level, which starts at 0 on day zero and increases by 1 each day to a maximum of 80. When the players meet a nun or other convent inhabitant for the first time, or a significant time has passed since they last met, the GM rolls 1d100. If the roll is equal to or less than the current Corruption Level, the NPC has been corrupted and now serves the Demon. The Corruption Level, which can be lowered and raised by PC actions, also affects location encounters and the Demon's freedom of movement. 

As events escalate at the convent, the PCs are able to learn more about the lust demon. Five demons are written up in the scenario and the GM decides which one it is. Learning its true name makes it easier to banish. Each also has a "fascination", an activity such as adultery or sex in a sacred place, that will keep it distracted and stop it from attacking you, which can maybe buy enough time for a banishing ritual.
