Special Thanks to Railun for sharing their rules from their game for this:
Rumors are as integral to the Courts as the sword is integral to the Battlefield. Even the youth have learned of their importance.
To Spread a Rumor:
It is a TN 3 (Air 2) Courtesy or Games skill check. Limit Once Per Time Slot.
To Track a Rumor:
It is a TN 3 (Water 2) Courtesy or Games skill check. This TN may be increased if the person spreading the rumor uses the Rustling of Leaves shuji. This may be attempted once per time slot.
