> It sounds like you wanted pre warning that x could happen in the game which is fair but baring some NSFW stuff it's it assumed that anything can happen in a typical dnd game?
Very common advice for TTRPGs, especially with a group that isn't established with implicit boundaries, is, and has been for w couple of decades, to have a pre-session in which this stuff is discussed openly, with both the GM raising anything they expect to be an issue and players putting forward anything else that is an issue for them, to mitigate this. You can't anticipate everything this way, but “everything goes” is recognized as potentially problematic.
It's a bit more challenging to handle mid-campaign additions non-disruptively, and I expect that even at tables that are otherwise good at this that is somewhat more often a problem, though.
