Add a new dynastic rule called “Challenges” and give it the following text

There is a publicly tracked list of challenges. Each challenge is a statement that a fragment may or may not meets such as “The fragment does not contain the letter e”. That determination must be determinist and depend solely on the text of the fragment in question and/or the text of the story (So, “The fragment only contains words already included in the story” is fine but “The fragment contains the name of its author” or “Roll a DICE100 if the result is 1, the fragment meets this challenge” is not).

As a Story Action that can only be performed when there is an open Open Judging, a Storyteller may add a new challenge

When the Publisher posts a new judging, each Storyteller receives one point for every challenge which is met by the fragment they authored they authored for that challenge (the Publisher should privately inform each Storyteller of the points received this way). Then, any challenge which at least one fragment met is removed from the list of challenges.
