By the year 2335 many cultures and species were living and working through the known universe. That universe covered numerous planets and many light years of distance and most were only reachable by faster than light (FTL) vessels. This did not hamper travel to and from as faster than light capability had long been acquired and distributed. Any world that had, in any way on their own, already reached into or explored outer space in any fashion had the option of receiving or rejecting this FTL knowledge.
It was found that no matter what species was encountered, the problems they experience were present in almost all cultures. Outbreaks of hostility was somehow common to all and the prevention of those hostility fell on the Universal Galactic Governing Board (UGGB). This board was made up of representatives, one from each world that had accepted the FTL capability. This conglomerate of species general had only one conferences every five years to record changes in delegates and address universal problems. On the other hand, an emergency meeting could be called at any time if something problematic was encountered that threatened security and peace.
The UGGB was not designed to be the peace negotiators nor were they schooled in that capacity. They, however, did setup an organization with this single purpose. This organization's only duty was to try to negotiate a peaceful settlement between worlds who were, for whatever reason, at war with each other. These brave souls who went into harm's way were called Coordinators.
