Delta Quadrant The Delta Quadrant was the common designation for one - quarter of the Milky Way Galaxy . This quadrant was adjacent to the Beta Quadrant and to the Gamma Quadrant . The quadrant ' s closest point to the was located in the galactic core , which was located approximately 60 , 000 light year s away . ( , " Season 7 " ) The Delta Quadrant was home to thousands of species , including the Kazon , Talaxian s , Ocampan s , Borg , Vidiian s , Hirogen , Krenim , and many others . Human s were first planted in the Delta Quadrant by a race known as the Briori around the year 1937 as a form of slave labor . The slaves rebelled and their descendants built a new civilization on a class L planet . ( ) The Delta Quadrant was first visited by Humans of their own free will on stardate 32629 . 4 , when the followed a Borg vessel into a transwarp conduit . ( ) The first Starfleet mission into the Delta Quadrant occurred during an inspection of the Barzan wormhole in 2366 . ( ) Due to the considerable distance between the Alpha and Delta Quadrants ( an starship would take thirty years to reach the edges of the quadrant at its maximum warp velocity ) , the Federation knew very little about this region of space until 2371 , when the starship was pulled into the quadrant by an alien force called the . When contact was reestablished with the starship in 2374 , hundreds of kiloquad s of data on the region was received , increasing the Federation ' s knowledge of the quadrant immensely . When Q discovered " Voyager " , he assumed Quinn was responsible for transporting it there , stating that Humans weren ' t supposed to be in the Delta Quadrant for another hundred years . ( ) When " Voyager " returned to Earth from the Borg transwarp network in 2378 , the Federation ' s knowledge of the quadrant was expanded considerably . ( ) History . Millions of years before recorded Human history , it is speculated that the Voth may have left Earth and traveled to the Delta Quadrant where they established a powerful and reclusive civilization . ( ) Around 45 , 000 years ago , a humanoid species from the Delta Quadrant traveled to Earth , where they discovered a tribe of Humans . Though the Humans at this time had no language or tools , the humanoid visitors admired their respect for the land . The humanoids continued to visit Earth for thousands more years , seeing the tribe they visited become the Native American people , and they came to worship the humanoids as the Sky Spirit s . The humanoids stopped visiting when European settlers started to conquer their land . ( ) Around the 3rd century , an epidemic known as Phage spread throughout the Vidiian Sodality , reducing a previously renowned culture to subsisting on organ piracy and slave labor . ( ) In the 15th century , the Vaadwaur controlled many colonies and exerted influence across much of the Delta Quadrant , if not further , via a series of underspace corridor s . In 1484 an alliance of species led by the Turei destroyed the Vaadwaur empire , forcing survivors to undergo cryostasis in the hopes of preserving their society . ( ) Jal Sankur united the Kazon sects in 2346 to overthrow their enslavers , the Trabe . Virtually all Trabe territory fell under control of the various sects , which soon began fighting among each other . ( ) In 2369 , Q told Vash that there was still the Delta Quadrant for her to explore with him . ( ) Prior to 2371 , an entity known as the Caretaker , while not claiming any specific territory " per se " , was a major factor in the sociopolitical climate near the outer rim of the Delta Quadrant , in the midst of Kazon space . ( ) 24th century political makeup . The greatest power in the Delta Quadrant , until at least 2378 , was the Borg Collective . In addition to a vast swath of territory which they had completely assimilated , the Borg used a transwarp network to routinely visit different points scattered throughout the quadrant . Following the Borg - Species 8472 War , the insurrection led by Axum , the destruction of a part of the transwarp network and the destruction of Unimatrix 01 , it was unclear how the Borg ' s status in the Delta Quadrant had been altered . ( ) Other alien species that controlled significant areas of the quadrant included , among others , the Vidiians , the Devore , the Kazon , the Voth , the Hirogen , the Hierarchy , and the Malon . Species 8472 had also established a presence in the Delta Quadrant until they returned to fluidic space . ( ) The political power of the Krenim Imperium depended largely on its temporal weapons , and as such its influence may have been altered dramatically by its own manipulation of the timeline . ( ) Appendices . Background information . The Delta Quadrant was originally suggested as the setting for by Michael Okuda . On , he sent a memo to Rick Berman that stated , " " Since the Gamma Quadrant is the province of ships from DS9 , suggest that this new show be set in the Delta Quadrant . One of the few things we know about the Delta Quadrant is that the Borg homeworld is located somewhere there . This might present opportunities for the Borg to be recurring bad guys . " " ( " " , pp . 207 - 208 ) Although fan lore and non - canon ical novels had situated the Borg as residing in the Delta Quadrant , they were first canonically cited as residents of the region in . ( " " , p . 189 ) That " Star Trek " film was released about three years after Okuda ' s memo to Berman . The Delta Quadrant is the only named galactic quadrant referenced in . It is referred to in , again in connection with the Borg .
