Solar Echoes: The Star Legation

Soon after the alien races began to explore outside their own star systems, they discovered each other. Hostilities grew into skirmishes and eventually, wars. However, some still desired peace. We've been taught that the Interstellar Union was formed in the year 1,023 LN. And we've been told of the human, Trey Donovan, who led the peace legation to unite everyone across the stars.

Details beyond that are varied and embellished, but we do have records of Trey's past. This man, now considered a legend, was no diplomat. He grew up in entirely human-centric surroundings and had never ventured beyond human territories. He was banished to an exile colony after a dishonorable discharge from the military. He received no training for the peace legation that he supposedly led. Trey's only known redeeming quality was his leadership and success in bringing law to a planet overrun with criminals.

How did this man travel to alien worlds and speak before powerful leaders? How was this human able to convince those alien leaders to send a representative with him to join the Interstellar Union? How did he survive the dangerous journey through space among an alien crew, several which were technically still at war with each other? There are still many unanswered questions about Trey Donovan and his journey across the universe. What really happened aboard that starship?
