Illustrated backstory
After four centuries of conflict and chaos, Solsys finally sees the dawn of a new network of civilizations: the Federation of Worlds, later to be known as the First Federation. It is the result of cooperation between humans and the many new Terragen clades, in symbiosis with the transapients. This new, powerful, idealistic metacivilization, powered and inspired by a network of religions and ideologies centuries or even millennia old, knits together the diverse societies that have arisen since the end of the Technocalypse. The Federation's synthesis is so powerful that even former interstellar colonies that had gone their way for hundreds of years are swept into its orbit when the Federation makes contact.
