Add a new Rule to the Ruleset, called Grudge, with the following text:

Each Prisoner can have up to one Grudge, which is tracked in the GNDT. A Prisoner’s Grudge must be the name of one other Prisoner.

As a daily action and so long as they are not Party to a Confession, a Prisoner may Change their Grudge. This stands for changing or clearing their Grudge.

Whenever a Prisoner’s is the Accomplice in a Confession in which their Grudge is a Suspect, and - as a result of that Confession - their Grudge’s Sentence increases, that Prisoner may Roll On their Grudge within 24 hours of the resolution of that Confession. A Prisoner Rolls On another Prisoner by increasing their Sentence by 1.
