Someone did. I thought it was him?
It was made up by
@overgeeked.
@hawkeyefan has twice pointed out that it was made up: posts 515 and 564. (EDIT: and a third time in post 566.)
The D&D DM has to determine outcomes. If the party is sleeping 8 hours while the enemy was hot on their trails he needs to determine what happens in that time so that he can frame the next important scene to the players.
Why do you say the enemy was "hot on their trails"?
In any event, in determining outcomes, is the GM obliged to have regard to players' declared actions for their PCs. Their intents? Their invocation of an ability that states "You can find a place to hide, rest, or recuperate among other commoners, unless you have shown yourself to be a danger to them. They will shield you from the law or anyone else searching for you, though they will not risk their lives for you"?
I mean, the GM can always
decide that the hiding PCs are a risk to the lives of the NPCs they are hiding with, by making decisions about what other NPCs know and discover and do - ie via solitaire play. To what extent are they obliged to confine their solitaire by reference to what the players have declared as actions for their PCs, and what abilities they have invoked?
If the GM can
conceive of or
imagine a way in which the NPCs providing haven might be subject to risk or threats, as that sufficient to make it reasonable GMing to bring that scenario to pass? If so, the ability has no purpose at all, does it, except perhaps to invite the GM to imagine the PCs taking safe haven with some commoner NPCs.
In this particular case he chose to frame the scene as the Duke's men surrounded the PC's over night. There are other judgements that could be made. Personally, I would have given the final watch a perception check to notice this happening and started the scene there. I think it was a mistake not to do this. Would that single check in your mind have been enough to avoid Mother May I?
In my view, no. Because the point is that the players ability that permits
hiding, resting and being shielded from searchers is having an effect on the fiction only to the extent that the GM decides that it does in the course of imagining all the things that the NPCs are doing. As adjudicated by
@hawkeyefan's GM the ability had no teeth at all, and that is what makes it "Mother may I?"
