First Ones
The First Ones is the collective name of a group of aliens from the television science fiction drama Babylon 5.
Overview
The First Ones are the ancient alien races of the galaxy, the first organisms to achieve sentience and the first to become spacefaring. Of these races, Lorien's was the first, with Lorien himself being the first among them. They were followed by the Shadows, who were discovered and taught by Lorien's people. Other races also appeared, among them the Vorlons, the Walkers at Sigma 957, and others. Together they achieved great enlightenment and technological advancement. Over time, however, many of these races left the galaxy, some dying out, others heading beyond the galactic rim into the void of intergalactic space. Of the few who stayed behind, most remained for reasons known only to them, but of these remaining races, two would be charged with the guardianship of the younger races (the Minbari, Narn, Centauri, Humans and others). These two are the Vorlons and the Shadows. The others after the Great War 10,000 years ago remained in isolation and allowed only Lorien to visit.
