The betan were the only wave to be explicitly mandated by the pearl people to travel to a preoccupied system
to aid another group
in seting up a foundation for serving the waves of ships who would follow them.
When they got there, however, they found that the Alphi
had not yet arrived and they would have to dictate the system's direction. This disheartened the unified leadership as they were ill equipped for such an undertaking. And because of Gammium's unnavigability, had no safe alternative to travel to.
Several factions evolved who primarily sort to explore the voids on either sides of the spine
, only to comeup empty handed. Eventually, dominant groups arose who unanimously abandoned the pearl directive and disappointedly separated into five factions typical of past human behaviours.
