[Yeah, at the start Erin had been planning to just find a vehicle and ditch this place. The best laid plans never work. Change of plans now, and not necessarily because there's no vehicle available!

...although she sure wouldn't be against having a potential escape as plan B, if she finds a way...]

That depends a lot on what's being summoned. Demons, entities, monsters, all that have their own different demands and what not.

Best way to stop it is make the cult unable to meet their demands. That's why I was trying to mess up the pentagram that other time, some demons like their little symbol things spick and span.
