First Contact with Calypsians

Diplomatic action

Humanity's exploration of the planet Calypso with the Arete mission yielded an astonishing discovery: an indigenous species of sophont, labeled Calypsians on account of their unpronounceable native name. The discovery of another extant sapient species in the universe produced an unprecedented and profound paradigm shift in humanity: the revelation that humans were not alone in the universe was a joyful one. Several decades after the Arete mission's safe return to Earth, humans received a transmission from the Calypsians, kick-starting a chain of long-term back-and-forth correspondence between the two species that eventually lead to their alliance with the United Spacefaring Sophonts Coalition.
