Edenians

Edenians are a race of remnants they search for the cause of the Great filter after their first Contact scenario was arriving at a dead civilizations world and when they returned they found their own civilization destroyed. So they continued moving forever running trying to escape this invisible filter. forsaking their own bias to hold more of their population in that migrant ships.   As the years went by they found lesser species and some were doomed, and the sub sect sought to save them as there was no one to save their own people. And if a race is lucky they’ll be taken to a new world courtesy of the Edenian.   They continued this becoming pacifistic and this continued for hundreds of years ...until they met humanity.
