Seems rather specific. As in, apparently it requires active non player characters, excluding myst-likes. But we'll roll.
Does this include stories where whether the delusion is a delusion is ambiguous? (E.g. Fran Bow)
There is actually no requirement that there be any other characters. Just if there are, they also know the belief is false
And no, there is no ambiguity, the belief is very clearly false.
right, so no "the character is you". Thanks for the clarification.
