From Traveller Wiki - Science-Fiction Adventure in the Far future

The region known as Charted Space is hundreds of parsecs across, but it is a mere droplet in the vast ocean of stars that is the galaxy. However, Charted space is unusual for one important reason – it has sentient life. Non-sentient life has been found beyond the little bubble of well-traveled space inhabited by the various major and minor races, but as far as explorers have traveled in any direction they have not found a sentient species that did not originate in Charted Space. The reason for this island of life among a billion barren worlds is unknown.

Of course, scientists concede that there may be sentient life out there, beyond the explored regions, who have not yet been contacted. There are groups of humans living on far-distant worlds at the edge of Charted Space. But they did not originate there; they were transported from Terra long ago for reasons unknown by a group or species known now as the Ancients.
