At the CotI boards, there is an interesting thread about replacing one of the coyns for the major races with something else. E.g. a coyn for “the Virus” or IMTU (where the virus doesn’t exist) a coyn for the Hhkar. Since I am an evil referee, the coyn I would replace would be the humaniti coyn, (and this would happen all over known space). 😈

This could be the start of an interesting campaign where the PCs try to save the future of humanity. Only the PCs and a number of scientists would know about the change, and the authorities will not listen to their warnings…
