Can anyone clarify if a supernatural needs to be reinvited in whenever they re-enter a threshold or do they get free access after one time? cant remember anything about it from the first RPGs section on thresholds.
I'd go with: it lasts as long as it's intended to last.
I like this the best. Unless you're giving a standing invitation (as The Mighty Buzzard said). When I welcome people over to my house, I invite them in every time. There are certain people, like really good friends and extended family, who can walk in without the formality of being invited in. I think you can also withdraw invitations as well.
Good calls, those.
They made me wonder, however, if one can actively withdraw an invitation once it's given?
I'd actually go for yes and maybe. Because, well, someone with true faith should darned well be able to drive off or weaken things with "You are no longer welcome here." A wizard with a good conviction might be able to do similar - though I'd consider charging them a fate point for it. Ordinary people? Probably not so much.
I like this. I wonder if the "rules of hospitality" apply here.I thought about that too but it doesn't really jive with canonical examples. If you could rescind an invitation because of a violation of the laws of hospitality, I don't think we'd see the same level of paranoia about inviting something using the form of a friend in. Don't mean it's not possible, just that I don't consider it probable.
The only issue I have with allowing you to retract an invite after the creature/person has crossed the threshold is it takes away the scariness of "accidently" inviting something BAD into your house....so maybe really limiting it to certain situations like the ones wyvern pointed out.
I'd go with: it lasts as long as it's intended to last.
According to the books, you can have a standing invitation. Harry has entered Murphy's house with it's powerful threshold without issues to 'water her plants,' for instance.
